Free PDF Converter Online, No Upload — Convert Right Here in Your Browser
This is a PDF converter online with no upload: it runs entirely inside your browser on open-source PDF engines, so your files never leave your device: no upload, no account, no watermark, and no page limit beyond your computer's memory. Merge, split, rotate, crop, delete pages, number, compress, sign, watermark, redact, fill forms, add text, password-protect or unlock a PDF; OCR a scan; repair or compare files; impose booklets; turn images, HEIC, SVG, JPEG XL, TIFF, Word and Excel files into PDF; or convert a PDF to JPG, PNG, TIFF, JPEG XL, text, Markdown, HTML, Word, Excel or PowerPoint — thirty-two tools, and once the page has finished loading, they keep working offline. Below the tools there is also a PDF reader with search, a visual page organiser and "Ask your PDF".
Add two or more PDFs in the order you want them combined. Use the arrows to reorder.
Private by design: processing happens on your device with open-source libraries (Mozilla's pdf.js, pdf-lib and, for TIFF files only, UTIF.js) served from this site — no third-party servers, and we never see your files. Only process files you have the right to modify. Scanned PDFs have no text layer — run the OCR tool first to make them searchable or convertible to Word.
Free, no ads, no upsell. If it saved you a trip to a paid converter, you can buy the developer a coffee — it funds new tools and keeps this one free. ☕ Buy me a coffee

- No upload, ever The file is read by your browser and the result is generated on your machine — you can even switch off Wi-Fi once the page has finished loading.
- No limits, no watermark No daily quota, no file-size cap, no account. Speed depends only on your device.
- Install it as an app Add it to your home screen or desktop and it opens PDFs straight from your file manager or share sheet — fully offline, including OCR once a language has been downloaded.
- Open source you can audit Built on Mozilla's pdf.js and pdf-lib, the same engines behind Firefox's PDF viewer and countless apps.
- Accessible by design Every tool works with a keyboard alone and announces progress, errors and results to screen readers; it respects your reduced-motion and dark-mode settings.
- Honest about its limits PDF to Word keeps text, paragraphs and headings but simplifies layouts; there is no OCR. For pixel-perfect output, use a ranked tool below.

Free PDF Reader Online — Read, Search and Organise Pages Without Uploading
A free online PDF reader with no upload: open a PDF from your device and read it right here with smooth continuous scrolling, zoom, rotation, thumbnails, bookmarks and find-in-document — then switch to Organise to reorder, rotate, duplicate or delete pages and export a new PDF, or to Ask your PDF to find the passages that answer a question. Everything is rendered by Mozilla's open-source pdf.js inside your browser, so your document never leaves your computer: no account, no watermark, no file-size limit beyond your device's memory, and it keeps working offline once the page has loaded.
- Read Continuous scrolling, zoom in/out, fit width or fit page, pinch to zoom, rotate, page thumbnails, outline/bookmarks, document properties, full screen and print — plus a text layer so you can select and copy text.
- Find in document Search every page with a live match count, next/previous, match-case and highlighted hits. Press Ctrl+F while reading.
- Dark page mode Inverts the page itself (not just the interface) for comfortable night reading; follows your light/dark/system preference everywhere else.
- Organise pages Drag pages into a new order (or use the keyboard), rotate, delete, duplicate, insert blank pages, add pages from other PDFs, undo, then export a new PDF built on your device with pdf-lib.
- Ask your PDF Type a question and get the five most relevant passages with page numbers and a "jump to page" link — ranked by BM25 on your device, no AI service, nothing uploaded. Scanned PDFs without text are pointed to the OCR tool.
- Accessible by design Every control is labelled and keyboard-reachable (arrows, Page Up/Down, Home/End, +/−, Esc); page changes and search results are announced to screen readers; reduced motion is respected.
- Open with and share to Install the site as an app and PDFs can be opened with it from your file manager or shared to it from other apps — they still never leave your device.
Private by design: rendering, search and page export happen on your device with open-source libraries (Mozilla's pdf.js and pdf-lib) served from this site. Only open files you have the right to use. Scanned PDFs show as images: use the OCR tool to make them searchable first.

Image & File Tools Online, No Upload — Compress Photos, Scan Documents, Passport Photos, ZIP, QR and More
The jobs people do right before or after converting a PDF, with the same rule as the converter above: everything runs on your device. Convert images between JPG, PNG, WebP, JPEG XL and TIFF; compress a photo to a target size (under 200 KB for a form, under 50 KB for a portal); clean up and deskew phone scans or run the document scanner straight from the camera; make a passport or ID photo with a print sheet; strip EXIF/GPS data; create or extract ZIP files; batch-rename, inspect, hash and de-duplicate files; split a large file for email; generate or read QR codes; and turn text or Markdown into a PDF. Outputs appear in "Recent files" so you can feed them straight into the PDF tools.
Convert between JPG, PNG, WebP, JPEG XL and TIFF.
Private by design: images are decoded and re-encoded by your browser; ZIP, hashing and QR use small open-source libraries served from this site (licences). Nothing leaves your device, and once loaded the tools keep working offline.

The 10 Best PDF Converter Online Tools in 2026
These are the ten services we recommend first when someone searches for a PDF converter online. Every pick converts PDF to Word, Excel, PowerPoint, and images (and back) in the browser with no software install. Rankings weigh conversion fidelity, free-tier generosity, price, speed, and file-privacy policy — full criteria in our methodology. Most offer both a free tier and a paid plan; prices below were re-verified on October 22, 2026.
-
Adobe Acrobat Online
Best overallWeb · iOS · AndroidStandard $14.99 · Pro $19.99/moAdobe invented the PDF format in 1993, and its browser-based Acrobat tools remain the fidelity benchmark: complex layouts, fonts, and tables survive PDF ↔ Word/Excel/PowerPoint conversion better than on any rival we tested. Free tier covers limited daily tasks with an Adobe account; paid plans add OCR, redaction, and e-signing. Verified October 22, 2026: Standard $14.99/mo and Pro $19.99/mo on an annual plan ($24.99 / $29.99 month-to-month), plus a new Acrobat Studio tier at $24.99/mo.
Best for: flawless conversion quality on documents that must look identical.
Free: limited daily tasks Visit Acrobat (opens in new tab) -
iLovePDF
Best valueISO 27001Premium $60/yr (≈$5/mo)Twenty-five-plus tools, batch processing, desktop and mobile apps, and one of the most generous free tiers in the category. iLovePDF is ISO/IEC 27001 certified and GDPR-compliant, with files deleted from its servers after processing. Premium — $60 a year, or $9 month-to-month — unlocks larger files, OCR, and no ads for well under what Smallpdf charges.
Best for: everyday conversions at the lowest paid price.
Free: per-tool task caps (1–25 per task type) Visit iLovePDF -
Smallpdf
Easiest to use30+ toolsPro $15/mo (monthly)The cleanest interface of any online converter — drag, drop, done. Smallpdf offers 30+ tools, a Chrome extension, Google Workspace integration, and AI summarization. ISO 27001 certified with TLS encryption throughout. The free tier is the catch: two tasks per day, so heavy users will need Pro (about $10/month billed annually).
Best for: non-technical users who want zero learning curve.
Free: daily limits per tool Visit Smallpdf -
Sejda
Privacy pickAuto-deleteWeb from ~$7.50/moSejda publishes one of the clearest privacy policies in the business: uploads are processed over TLS and automatically deleted within hours, never analyzed or resold. Its 30+ tools include true in-browser PDF text editing and OCR. Free tier allows 3 tasks per day up to 50 MB / 200 pages; a desktop app handles fully offline work.
Best for: privacy-conscious users doing occasional conversions.
Free: 3 tasks/day · 50 MB Visit Sejda -
CloudConvert
Best for automation200+ formatsFree 10/day · credit packagesThe engineer's choice: 200+ formats, granular control over output settings (DPI, page ranges, OCR language), a well-documented API, and Zapier/Make integrations. Conversions run in sandboxed containers and files are never shared. The free tier gives 10 conversions a day on files up to 1 GB; beyond that you buy credit packages (they never expire) instead of a subscription.
Best for: developers and anyone automating document workflows.
Free: 10 conversions/day · 1 GB Visit CloudConvert -
pdfFiller
Best for businessSOC 2 · ISO 27001From $8/mo (annual)More than a converter: pdfFiller pairs conversion with a full editor, fillable forms, and legally binding e-signatures, all under SOC 2 Type II and ISO 27001 certification. There's no permanent free tier — just a 30-day trial — but for teams that process contracts and forms daily, the $8/month annual Basic plan replaces several separate subscriptions.
Best for: businesses handling forms, contracts, and signatures.
30-day trial · no free tier Visit pdfFiller -
Xodo
Best cross-deviceBy ApryseFrom $7.99/moBuilt by Apryse (the SDK company whose PDF engine powers thousands of apps), Xodo combines capable web converters with the highest-rated mobile PDF apps on iOS and Android. Core viewing and annotation stay free; the free tier allows one action a day, and conversion beyond that needs Xodo Web ($7.99/mo billed annually) or the Document Suite ($8.99/mo). Documents sync cleanly across phone, tablet, and browser.
Best for: people who switch between phone and desktop all day.
Free: 1 action/day Visit Xodo -
Soda PDF
Web + desktop comboOCR includedFrom ~$7/mo (annual)Soda PDF's differentiator is licensing: one subscription covers both its online tools and a full Windows desktop editor, with OCR and cloud-drive integrations (Google Drive, Dropbox, OneDrive). The free online tier is tight — around two files per day with small size limits — so treat it as a trial for the paid bundle rather than a daily driver.
Best for: one license across browser and desktop.
Free: ~2 files/day Visit Soda PDF -
Zamzar
Most formatsSince 2006From $12/moConverting files since 2006, Zamzar supports over 1,100 format pairs — handy when the job isn't just Office documents but eBooks, CAD files, or legacy formats. No account is needed for free conversions (2 files/day, 50 MB each). Paid plans start at $12/month (Basic, 200 MB files) and $19/month (Pro), so it earns its slot on breadth and reliability rather than value.
Best for: unusual formats other converters reject.
Free: 2 files/day · 50 MB Visit Zamzar -
Convertio
Fast one-offs300+ formatsLite $11.99/mo · $6.99/mo annualA no-nonsense converter covering 300+ formats with direct import from Google Drive and Dropbox. The free tier allows 10 conversions per day at up to 100 MB — enough for casual use, though files route through Convertio's servers, so skip it for confidential material. Paid plans start with Lite at $11.99/month, or $6.99/month billed yearly (1 GB files, 1,000 credits) and raise limits and processing priority.
Best for: quick conversions straight from cloud storage.

$0 — no watermarks, no tricks
PDF Converter Online Free: The 10 Best Free Tools in 2026
Searching for a PDF converter online free of charge usually ends in one of two traps: a "free" tool that watermarks your file, or a daily limit you hit on the second document. Every pick below avoids both. Each one converts PDFs at no cost, adds no watermark, and — for our top picks — needs no account at all. Where a free tier has limits, we state them exactly.
-
PDF24 Tools
100% freeUnlimitedNo signupThe rare tool that is completely free with no daily caps, no file-size ceilings, and no watermarks — across all 40+ tools. PDF24 is run by Germany's Geek Software GmbH, operates under GDPR, and funds itself with unobtrusive ads. A free Windows desktop app adds a virtual PDF printer and offline OCR. Nothing else on this page matches its free offer.
Best for: everyone — the best free PDF converter online, full stop.
Free: unlimited · no watermark Visit PDF24 -
PDFgear
100% freeAI copilotWeb + desktopPDFgear gives away what competitors charge for: full conversion to and from Word, Excel, PowerPoint and images, OCR, compression, and an AI copilot — free on the web with no signup, and free in desktop apps for Windows, macOS, iOS, and Android. There is no premium tier at all. The interface is plainer than Smallpdf's, which is the only real trade-off.
Best for: a free desktop-grade PDF suite without paying anything, ever.
Free: everything included Visit PDFgear -
TinyWow
100% freeNo signupAuto-delete 15 minOver 200 free tools — PDF, image, video, and AI writing — with no account, no watermarks, and files auto-deleted from servers within an hour. TinyWow is ad-supported; the optional Premium plan ($20/month, or $15/month billed yearly, as of October 2026) removes ads and captchas and adds priority processing but unlocks no extra tools. Conversion quality on standard Office documents is solid, though there's no OCR for scanned files.
Best for: zero-friction conversions when you don't want to register anywhere.
Free: unlimited, ad-supported Visit TinyWow -
iLovePDF (Free tier)
Generous free tierISO 27001Mobile appsThe most generous free tier among the big freemium brands: multiple conversions per day at quality identical to the paid plan, with no watermarks on standard tools. You get the same ISO 27001-certified infrastructure as Premium users. Limits apply to file size and batch volume — if you hit them regularly, Premium at $60 a year (about $5/month) is the cheapest upgrade path in the category.
Best for: polished, reliable free conversions with room to grow.
Free: daily allowance Visit iLovePDF -
Adobe Acrobat Online (Free tools)
Free daily tasksBest-in-class engineAdobe's free browser tools give you the same conversion engine that powers Acrobat Pro — the most accurate PDF↔Word conversion available — at no cost for occasional use. You'll need a free Adobe account, and daily task limits are real, but for a contract or CV that must convert perfectly, one free Acrobat conversion beats ten mediocre ones.
Best for: the occasional document where fidelity matters most.
Free: limited tasks, account required Visit Acrobat -
FreeConvert
20 conversion-minutes/dayBig filesFreeConvert meters free use in processing time rather than file count: 20 conversion-minutes a day (about 20 typical files) with up to 5 minutes per file, no account needed — which still makes it the free pick for image-heavy reports, scanned books and presentation exports that other free tools reject at 50–100 MB. Paid plans start at $12.99/month (Basic, 1.5 GB files). Free jobs queue behind paid ones, so large files can take a few minutes.
Best for: huge files that break every other free converter.
Free: 20 conversion-minutes/day Visit FreeConvert -
PDF Candy
40+ free toolsDesktop appMade by Icecream Apps, PDF Candy offers 40+ tools including OCR — rare on a free tier. The free plan's quirk is a cooldown timer between tasks rather than a hard daily cap: fine for one-at-a-time work, frustrating for batches. A one-time-purchase desktop version removes all waiting and works offline, making it a budget favorite.
Best for: free OCR and a wide toolset if you can pace your tasks.
Free: cooldown between tasks Visit PDF Candy -
PDF2Go
Free: 3/hourConvert from URLPDF2Go's party trick is converting a document straight from a URL or cloud drive — no download-then-reupload dance. The free tier allows roughly three conversions an hour at up to 50 MB, with standard tools (convert, compress, edit, protect) and no watermarks. It's a dependable second option when your first choice is rate-limited for the day.
Best for: converting files directly from a link.
Free: ~3/hour · 50 MB Visit PDF2Go -
Canva
Free planDesign-firstCanva approaches PDF conversion from the design side: import a PDF and it becomes a fully editable design — text, images, and layout elements you can restyle with 400+ templates — then export back to PDF, PNG, or PowerPoint. The free plan covers all of this. It won't preserve complex Word formatting like a dedicated converter, but for visual documents it's unmatched at $0.
Best for: flyers, decks, and visual PDFs you want to redesign, not just convert.
Free plan · account required Visit Canva -
Google Drive & Docs
Completely freeUnlimitedThe free converter hiding in plain sight: upload a PDF to Google Drive, open it with Google Docs, and the text becomes editable — including basic OCR on scanned pages — then download as Word, ODT, or PDF. Unlimited, free, and private to your Google account. Formatting on complex layouts will shift, but for text-first documents it costs nothing and never rate-limits you.
Best for: free PDF-to-editable-text with an account you already have.
Free: unlimited Visit Google Drive
Watermark check, August 2026: none of the ten free tools above stamped a watermark on our test conversions. If any "free PDF converter" you meet elsewhere adds one, close the tab — a watermark-free alternative always exists.

Decision guide
Free vs Paid PDF Converter Online: Which Do You Need?
Roughly 8 in 10 people who search for a PDF converter online are fine with a free tool. Here's the honest split, based on our testing:
STAY FREE A free converter is enough if you…
- Convert a handful of files per week — PDF24's unlimited free tier alone covers this.
- Work with standard Office documents rather than scanned paper (no OCR needed).
- Can accept daily limits or ads in exchange for paying nothing.
- Don't handle regulated or confidential material online.
GO PAID A paid plan pays for itself when you…
- Need OCR on scanned contracts, invoices, or archives — the most common paid trigger.
- Batch-convert dozens of files or need API automation (CloudConvert, iLovePDF).
- Require perfect layout fidelity for client-facing documents (Adobe Acrobat).
- Want e-signatures, redaction, or compliance certifications (pdfFiller, Acrobat Pro).
60-second guide
How to Use a PDF Converter Online (3 Steps)
Every online tool on this page follows the same three-step flow (the converter at the top skips step one entirely — nothing is uploaded). A typical 10-page document converts in under 30 seconds on a normal connection.
- Upload your file Drag the PDF into the converter (or pick it from Google Drive/Dropbox where supported). Check the file-size limit first — free tiers range from 50 MB (Sejda, PDF2Go) to 1 GB (FreeConvert).
- Choose the output format Word (.docx) for editing text, Excel (.xlsx) for tables, JPG/PNG for images, or PDF/A for archiving. If your PDF is a scan, pick a tool with OCR — PDF Candy and PDF24 offer it free.
- Download and verify Save the converted file and skim the layout: tables, fonts, and page breaks are where cheap converters slip. If fidelity is off, re-run the same file through Adobe's free online converter and compare.
Pro tip: converting to PDF is nearly lossless with any tool on this page; converting from PDF back to editable formats is where quality differs. That direction is what our rankings weigh most.
Privacy & security
Is It Safe to Use a PDF Converter Online?
Generally yes — with the reputable services above. Your file travels over an encrypted TLS connection, is processed on the provider's servers, and is deleted afterwards. But "generally" is doing real work in that sentence, so apply this checklist:
✅ Green flags to look for
- Published auto-delete window — TinyWow deletes within an hour; Sejda within a few hours; iLovePDF and Smallpdf after processing.
- Security certifications — ISO/IEC 27001 (iLovePDF, Smallpdf, pdfFiller) or SOC 2 Type II (pdfFiller).
- GDPR jurisdiction — EU-based processors like PDF24 (Germany) operate under strict data-protection law.
- A real privacy policy that names retention periods, not vague "we care about privacy" copy.
⛔ When not to upload at all
- Medical records, legal discovery, unreleased financials, or anything under NDA.
- Documents containing passwords, ID numbers, or biometric data.
- Files your employer's security policy forbids sending to third parties.
- For all of these, convert locally instead — use the no-upload converter on this page, an open-source tool you can self-host, or one of the offline desktop converters below.
When online isn't enough
Beyond the Browser: The Best Offline PDF Converters for Desktop (2026)
An online converter is perfect for occasional files. Switch to an offline desktop converter when you handle confidential documents (nothing leaves your machine), convert in bulk, work without reliable internet, or need pro features like redaction, PDF/A archiving, and high-accuracy OCR. These eight apps are the ones we'd actually install, ordered by overall value.

It renders, searches, rotates, deletes, inserts and moves pages, merges, extracts and splits files, handles AES-256 password protection, forms, comments, layers and attachments — all offline, with no account or telemetry. v0.4.0 shipped on October 8, 2026 and the project still calls itself alpha: editing existing text and non-Latin OCR are not there yet.
Best for: a free, auditable Acrobat replacement for organising, merging and splitting PDFs offline.

Stirling-PDF
Most toolsSelf-hosted · DockerOpen-coreThe heavyweight: over 94,000 GitHub stars, 50+ tools (convert, merge, split, OCR, sign, redact, compress, watermark, automate) and a private API, deployed with a single
docker runon your own server, as a desktop app, or on Kubernetes. Because processing happens on your machine, it is the usual answer when a company needs an "online" PDF converter that never sends documents to a third party. The project moved to an open-core model, so some enterprise features sit behind a paid tier — the community edition still covers everything most teams convert.Best for: teams that want a private, web-based PDF converter on their own infrastructure.

BentoPDF
Runs in the browser100% client-sideAGPL-3.0 · $79 commercialA browser-based PDF toolkit — roughly 16,000 GitHub stars — whose README promises that every operation runs in your browser with no server processing, the same approach as the converter at the top of this page. It lists 50+ tools (the feature tables run past 100 entries) across organising, editing, converting to and from PDF, and security, with heavier jobs handled by WebAssembly builds of PyMuPDF, Ghostscript and CoherentPDF that load from a CDN on demand. Use the hosted version at bentopdf.com or self-host the static files; the AGPL licence is free if you publish your changes, and a one-time $79 commercial licence covers everyone else.
Best for: a free online PDF converter where nothing is uploaded, with far more tools than ours.

PDF Arranger
Simplest desktop appLinux · Windows · macOSGPL-3.0A small Python/GTK desktop app (about 6,000 stars) that does one job well: drag pages between PDFs to merge, split, rotate, crop and reorder them visually. It is a front end for the pikepdf library, ships on Flathub, the Snap Store and as Windows and macOS builds, and is the tool to hand to someone who finds Stirling-PDF overkill.
Best for: non-technical users who want to rearrange and merge PDFs by drag-and-drop, offline.

LibreOffice
Best free Office-to-PDFWindows · macOS · LinuxMPL-2.0The free office suite is also the most reliable open-source converter to PDF: every Writer, Calc and Impress document exports to PDF or PDF/A, with tagged (accessible) output, and
soffice --headless --convert-to pdfbatch-converts whole folders from the command line. Opening a PDF in LibreOffice Draw also lets you edit text and export again, though complex layouts can shift.Best for: converting Word, Excel and PowerPoint files to PDF in bulk without paying anyone.

pdfcpu
Best CLIGo · single binaryApache-2.0A single-binary command-line tool and Go library (about 8,900 stars) that merges, splits, validates, optimises, encrypts and decrypts PDFs, stamps watermarks and page numbers, and extracts images, fonts and metadata. No GUI, no dependencies — ideal for scripts, CI pipelines and servers where a web app is unnecessary.
Best for: developers and sysadmins automating PDF processing from the shell.

qpdf
Structural toolkitC++ · every platformApache-2.0The veteran: a content-preserving transformation tool used inside many other projects (including pikepdf, which powers PDF Arranger). It linearises PDFs for fast web viewing, repairs damaged files, splits and merges pages, and adds or removes encryption — without ever re-rendering the content, so nothing is lost. Packaged in every Linux distribution and in Homebrew.
Best for: repairing, optimising and password-handling PDFs losslessly.

How this page relates: the free converter above is built on the same open-source foundations (Mozilla's pdf.js and pdf-lib, licences here) and follows BentoPDF's rule that nothing is uploaded. If you need OCR, Word output with layouts preserved, or dozens of tools in one place, self-host Stirling-PDF or use BentoPDF; if you want a desktop app, PdfCraft is the one to watch.

Straight answers
PDF Converter Online: Frequently Asked Questions
What is the best PDF converter online in 2026?
Adobe Acrobat Online is the best PDF converter online in 2026 for conversion fidelity, iLovePDF is the best value at $60 a year (about $5/month) for Premium, and Sejda is the strongest privacy pick with auto-deleted uploads. If you refuse to pay anything, PDF24 Tools leads with unlimited free conversions and no watermarks — or use the free converter on this page, which never uploads your file at all.
What is the best PDF converter online free of charge?
PDF24 Tools is the best PDF converter online free of charge: no daily limits, no file-size caps, no watermarks, and no account needed, operated from Germany under GDPR. PDFgear and TinyWow are the best runners-up — both are 100% free with no signup required.
Is it safe to convert PDF files online?
With reputable services, yes. Files transfer over encrypted TLS connections, are processed on secured servers, and are deleted automatically — within an hour at TinyWow, within hours at Sejda, and after processing at iLovePDF and Smallpdf, both of which hold ISO/IEC 27001 certification.
That said, never upload medical records, legal discovery, or NDA-covered files to any online service. Convert those on your own machine with an offline desktop converter.
Can I convert PDF to Word online free without signing up?
Yes. PDF24 Tools, TinyWow, PDFgear, and PDF2Go all convert PDF to Word free with no account. For scanned PDFs that need OCR, use PDF24 or PDF Candy. Google Docs also turns PDFs into editable text at no cost if you already have a Google account.
Do free online PDF converters add watermarks?
The good ones don't. None of the ten free tools ranked on this page added a watermark to our August 2026 test conversions. Watermarking today survives mainly on obscure converter sites and in "free trials" of some desktop software — if you meet one, switch to PDF24 or iLovePDF's free tier instead.
What's the difference between a free and a paid PDF converter online?
Free tiers handle standard conversions with daily limits (typically 2–25 tasks) and file-size caps (50 MB to 1 GB). Paid plans, usually $7–$20 per month, remove those limits and add OCR for scanned documents, batch processing, API automation, e-signatures, and priority speed. Most individuals never need to pay; most businesses eventually do.
What is the best offline PDF converter for desktop?
Adobe Acrobat Pro remains the industry standard at $19.99/month. Wondershare PDFelement is the best-value alternative at $89.99/year with a perpetual-license option, UPDF is the budget pick covering Windows, Mac, iOS, and Android on one license from $49.99/year, and PDFgear is the best completely free desktop converter. All process files locally — nothing is uploaded.
Can I convert a PDF without uploading it to a server?
Yes. The free converter at the top of this page runs entirely inside your browser using open-source PDF engines, so the file is processed on your own device and never sent to a server. For heavier work, PDF24's free desktop app and PDFgear also convert locally at no cost, and paid editors like PDFelement, UPDF, Foxit, and Acrobat Pro add professional features on top. Local conversion is the correct choice for confidential or regulated documents.
How do I convert a PDF without losing formatting?
Choose a converter with a high-fidelity engine — Adobe Acrobat preserved complex layouts best in our testing, with Foxit and Nitro close behind. Convert to modern .docx rather than legacy formats, run OCR first on scanned files, and always spot-check tables, fonts, and page breaks in the output before sending it on.
Why is PDF still the standard document format in 2026?
PDF renders identically on every device and never reflows by accident — which is the entire point. Adobe created the format in 1993 under co-founder John Warnock's "Camelot" project, and it became an open ISO standard (ISO 32000) in 2008, now at PDF 2.0. Back in 2015, Adobe's VP of Engineering already estimated 2.5 trillion PDFs in existence; a decade later the true count is far higher — which is why a good PDF converter online is one of the most-searched utilities on the web.
Is the free converter on this page really private?
Yes. It is built on Mozilla's open-source pdf.js and the pdf-lib library, both served from this site and executed by your browser; there is no upload endpoint, no account, and no file ever leaves your device. Once the page has finished loading (the engines download in the background), you can disconnect from the internet and it still converts; only rare PDFs that need extra font or character-map data fetch those on first use. The trade-off is that it does not do OCR, so scanned PDFs need one of the ranked tools with OCR instead.
Is there an open-source PDF converter online?
Yes. BentoPDF is an open-source (AGPL-3.0) PDF converter that runs entirely in your browser at bentopdf.com, with 50+ tools and no upload; Stirling-PDF is an open-core web app with 50+ tools that you host yourself with one Docker command; and PdfCraft, released in 2026 under MIT/Apache-2.0, ships desktop apps for every platform plus a WebAssembly browser build. The free converter on this page is also built on open-source engines (pdf.js and pdf-lib). See the open-source section for all seven picks.
What is the best PDF converter online with no upload?
A "no upload" PDF converter processes the file inside your browser instead of sending it to a server. The converter on this page works that way for nine jobs — merge, split, rotate, delete pages, page numbers, images to PDF, PDF to JPG/PNG, PDF to text and PDF to Word — with no account, no file limit and no watermark, and it keeps working after you disconnect. BentoPDF is the open-source alternative with more tools (also client-side), and PDF24's free desktop app or PdfCraft cover offline work on your computer. Anything that shows an upload progress bar, including most of the ranked services, is sending your file to a server, even if it deletes it afterwards.
Can I convert TIFF to PDF, or PDF to TIFF, without uploading?
Yes — both directions run in your browser on this page. "Images / TIFF to PDF" accepts single and multi-page TIFFs (scans and faxes using LZW, Deflate, PackBits or CCITT Group 4 compression) and makes one PDF page per TIFF page, keeping the scan's resolution if you pick "Same as image". "PDF to JPG / PNG / TIFF" renders every page into one multi-page TIFF at 72, 150 or 300 DPI, Deflate-compressed, which opens in Windows Photos, macOS Preview, Photoshop and document-management systems. TIFF support uses the open-source UTIF.js decoder, loaded only when you add a TIFF.
Can I compress a PDF online without uploading it?
Yes. The "Compress PDF" tool on this page recompresses the images inside a PDF on your device — choose Smallest (1200 px images), Balanced or Light — and reports the before/after size. Text, fonts and vector graphics are never altered, so pages stay sharp; a PDF that is already compact is returned unchanged rather than degraded. Scanned and photo-heavy PDFs typically shrink by 50–90%.
Can I sign, watermark or password-protect a PDF in the browser?
Yes, all three. "Sign PDF" lets you draw a signature with a mouse, finger or stylus (or type your name) and place it on the first, last or every page — a visible signature image, not a cryptographic certificate. "Watermark" stamps text such as CONFIDENTIAL diagonally, as a repeating tile, or as a header/footer line. "Protect" encrypts with AES-256 and can block printing or copying; "Unlock" removes a password you know. Nothing is uploaded for any of them.
Can I OCR a scanned PDF online for free without uploading it?
Yes. The "OCR scanned PDF" tool runs the open-source Tesseract engine inside your browser (WebAssembly) and produces a searchable PDF — your original pages with an invisible text layer — plus plain text or Word output. English, Hindi, Marathi, Gujarati, Arabic, Urdu, French, German, Spanish, Portuguese and Italian are available, singly or paired with English; each language file (1–2 MB) downloads once from this site and is then cached for offline use. Devanagari, Gujarati and Arabic-script text is written into the searchable layer with embedded Noto/Amiri fonts, so Hindi, Marathi, Gujarati, Arabic and Urdu scans become searchable in Chrome, Firefox, Acrobat and Preview just like English ones. Accuracy depends on scan quality: 300 DPI, straight, high-contrast scans give the best results.
Is there a free PDF reader online that does not upload my file?
Yes — the reader on this page opens a PDF in your browser with continuous scrolling, zoom, text selection, find-in-document, thumbnails, bookmarks and a dark page mode. The same reader has an "Organise" view for dragging pages into a new order, rotating, deleting and duplicating them across files, and an "Ask your PDF" view that finds the passages most relevant to a question, with page numbers — all computed on your device, with no AI service involved.
Can I convert a PDF to Markdown or HTML?
Yes. "PDF to Markdown / HTML" extracts the text layer and rebuilds headings, paragraphs, bullet and numbered lists, simple tables and links as clean Markdown (ideal for notes apps, wikis and AI tools) or a lightweight HTML page. Scanned PDFs need the OCR tool first.
Can I convert PDF to JPEG XL (JXL), or JXL to PDF, without uploading?
Yes — both run in your browser on this page. "PDF to JPG / PNG / TIFF / JXL" renders each page to a .jxl file, either lossy at quality 85 (typically 30–50% smaller than an equivalent JPEG) or mathematically lossless; "Images / TIFF / JXL to PDF" accepts .jxl files and embeds them one per page. The encoder and decoder are libjxl compiled to WebAssembly (about 2 MB, Apache-2.0), downloaded once from this site and cached for offline use. Note that most browsers still cannot display .jxl files natively — Safari 17+ can, Chrome and Firefox need a flag or extension — so previews here are shown as JPEG thumbnails.
Can I compress a photo to under 200 KB or 50 KB without uploading it?
Yes. "Compress / resize image" on this page lets you type a target size in KB — 200 KB for a job form, 50 KB for a government portal — plus optional maximum width and height, and it finds the highest quality that fits, shrinking dimensions only if it has to. It runs in your browser, so the photo never leaves your phone, and it reports the before and after size.
Is there a free passport photo maker that works offline?
Yes. "Passport / ID photo" crops to the official size for Indian passports and visas (2×2 in, 600×600 px at 300 DPI), US passports, UK/EU/Schengen 35×45 mm, 25×35 mm ID photos or any custom size, warns if the background is not plain and light, can keep the JPG under a file-size limit such as 50 KB, and makes a print sheet (4×6 in or A4) with cut lines. Everything happens on your device; nothing is uploaded.
Can I scan documents to PDF with my phone camera without an app?
Yes. "Document scanner" uses your phone camera through the browser (or any photos you already took), straightens and crops each page, improves contrast or converts to black and white, and combines the pages into one PDF — then the OCR tool can make it searchable. Install this site as an app and it works offline.
Can I create or extract ZIP files, hash files or find duplicates in the browser?
Yes. The file tools create and extract ZIP archives (Deflate and stored entries), batch-rename files with patterns, list file details (size, dimensions, DPI, PDF page count), compute SHA-256/SHA-1/SHA-512/CRC32 checksums, find exact and near-duplicate images, and split a large file into email-sized parts and join them back — all on your device.
Can I fill a PDF form, redact or compare PDFs without uploading them?
Yes — all three run in your browser on this page. "Fill PDF form" lists the fields of an interactive PDF, fills them and can flatten the result; "Redact" finds the words or phrases you list and rebuilds those pages as images so the text is truly removed; "Compare PDFs" produces a highlighted report of inserted and deleted text between two versions. Nothing is uploaded for any of them.
Can I convert Word, Excel or PowerPoint online without uploading?
Word (.docx) and Excel/CSV can be converted to PDF on this page with a simple, clean layout — headings, lists, tables, images — but not Word-perfect fidelity; for that use the application's own "Save as PDF" or the ranked converters. In the other direction, PDF to Excel extracts tables to .xlsx/CSV and PDF to PowerPoint makes one slide per page with the text in the notes. PowerPoint to PDF with fidelity is not offered here.
PdfCraft vs Stirling-PDF vs BentoPDF: which should I use?
Use Stirling-PDF if you want the most tools (50+, including OCR and PDF-to-Word) on a server you control; it needs Docker or a desktop install. Use BentoPDF if you want an online converter that never uploads your file — it runs in the browser and needs no install. Use PdfCraft if you want a fast native desktop app to view, organise, merge, split and encrypt PDFs offline; as of v0.4.0 (October 2026) it is still alpha and cannot edit existing text or convert to Word. For everyday merge, split, rotate and PDF-to-image jobs, the converter at the top of this page does the same with nothing to install.
Why trust this page
How We Rank Every PDF Converter
🧪 What we test
Each tool converts the same set of sample documents — text-heavy, table-heavy, and scanned — in both directions. We score output fidelity, then verify free-tier limits, current pricing, speed, and each provider's published file-retention policy.
⚖️ Independence
Only the desktop apps section contains affiliate links, all marked rel="sponsored" and disclosed above the list (full disclosure). Commissions never influence positions — the online top-10 lists carry no affiliate links at all, and the free converter on this page has no upsell.
🔄 Kept current
Prices, free-tier limits and the open-source section were re-verified on by reading each vendor's pricing page (or, where a page would not render, a dated third-party listing); Soda PDF, PDF2Go and Nitro still carry our September 18, 2026 figures and say so. We re-check quarterly and after major vendor announcements, and the date stamp only changes when the content actually has.
🚫 What this site does not do
No OCR of handwriting; no pixel-perfect PDF-to-Word layouts (the ranked commercial converters do that better); no cloud sync, accounts or file history beyond the "Recent files" shelf on your own device; no Word/Excel-to-PDF with full fidelity. Stating the limits plainly is part of being trustworthy.
✉️ Corrections
Vendors change prices and limits between our quarterly passes. Anything that has moved is corrected at the next re-check, and the visible "updated" date changes only when the content does.
