## Quick answer
The best PDF converter online in 2026 is Adobe Acrobat Online for conversion fidelity, with iLovePDF as the best value and Sejda as the privacy pick. The best PDF converter online free is PDF24 Tools — unlimited conversions, no watermarks, no account required. For sensitive documents, use the free converter on this page , which never uploads your file, or an offline desktop app. If you want open source, PdfCraft (desktop, MIT/Apache) and BentoPDF (runs in the browser, AGPL) are the 2026 picks.

## The 10 best PDF converters online (free and paid)
### Adobe Acrobat Online — Best overall · Web · iOS · Android · Standard $14.99 · Pro $19.99/mo
Adobe 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.

### iLovePDF — Best value · ISO 27001 · Premium $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.

### Smallpdf — Easiest to use · 30+ tools · Pro $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.

### Sejda — Privacy pick · Auto-delete · Web from ~$7.50/mo
Sejda 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.

### CloudConvert — Best for automation · 200+ formats · Free 10/day · credit packages
The 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.

### pdfFiller — Best for business · SOC 2 · ISO 27001 · From $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.

### Xodo — Best cross-device · By Apryse · From $7.99/mo
Built 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.

### Soda PDF — Web + desktop combo · OCR included · From ~$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.

### Zamzar — Most formats · Since 2006 · From $12/mo
Converting 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.

### Convertio — Fast one-offs · 300+ formats · Lite $11.99/mo · $6.99/mo annual
A 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.


## The 10 best free PDF converters online
### PDF24 Tools — 100% free · Unlimited · No signup
The 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.

### PDFgear — 100% free · AI copilot · Web + desktop
PDFgear 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.

### TinyWow — 100% free · No signup · Auto-delete 15 min
Over 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.

### iLovePDF (Free tier) — Generous free tier · ISO 27001 · Mobile apps
The 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.

### Adobe Acrobat Online (Free tools) — Free daily tasks · Best-in-class engine
Adobe'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.

### FreeConvert — 20 conversion-minutes/day · Big files
FreeConvert 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.

### PDF Candy — 40+ free tools · Desktop app
Made 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.

### PDF2Go — Free for everyday jobs · Convert from URL
PDF2Go's party trick is converting a document straight from a URL or cloud drive — no download-then-reupload dance. The free tier covers everyday jobs with no account (the site states limits on file size and volume rather than a fixed hourly number; a free account raises the allowance), with standard tools (convert, compress, edit, protect) and no watermarks; Premium is $6.42/mo billed annually, or pay-as-you-go. It's a dependable second option when your first choice is rate-limited for the day.
Best for: converting files directly from a link.

### Canva — Free plan · Design-first
Canva 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.

### Google Drive & Docs — Completely free · Unlimited
The 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.


## Best offline desktop PDF converters
### Wondershare PDFelement — Best overall value · Win · Mac · iOS · Android · $89.99/yr · $129.99 perpetual
The strongest Acrobat alternative for most people: full editing, conversion to 10+ formats, batch OCR in 20+ languages, form creation, and AI summarize/rewrite tools — at roughly half of Adobe's price, with a perpetual-license option Adobe no longer offers. Files never leave your computer.
Best for: Acrobat-level features without the Acrobat subscription.

### UPDF — Best budget pick · One license, 4 platforms · From $49.99/yr · $79.99 lifetime
One license covers Windows, macOS, iOS, and Android — the best cross-platform deal in the category. UPDF's modern interface hides serious tools: conversion to 15+ formats, OCR, batch processing, and an AI assistant for summarizing and translating documents. A one-time perpetual license (list price $79.99, verified October 2026; often discounted) costs about what Acrobat Pro charges for four months.
Best for: covering every device you own for the price of one app.

### Adobe Acrobat Pro — Industry standard · Win · Mac + web + mobile · ~$19.99/mo (annual)
Still the reference implementation: unmatched conversion fidelity, the best OCR in our testing, legal-grade redaction, PDF/A and accessibility compliance, and seamless handoff between desktop, web, and mobile. You pay for it monthly, forever — but if PDFs are your job, nothing else is as complete.
Best for: professionals whose documents can't afford a single glitch.

### EaseUS PDF Editor — Best lifetime deal · Windows · From $19.95 · lifetime option
A capable Windows editor-converter with OCR and 10+ output formats at an unusually aggressive price: a Pro plan from $19.95 (discounted from $29.95 on October 22, 2026), with yearly and lifetime licences that have historically sat around $50 and $80 — the cheapest "pay once, own forever" route to full PDF editing we recommend. No Mac or mobile versions, and no AI features, which is how the price stays low.
Best for: Windows users who hate subscriptions.

### Foxit PDF Editor — Business favorite · Win · Mac · $129.99/yr · $209.99 perpetual
The corporate world's favorite Acrobat alternative: fast, light on memory, with enterprise deployment tools, security policies, and an OCR engine trusted in regulated industries. Foxit sits between PDFelement's value and Adobe's completeness — the sensible pick when IT needs to standardize a whole team.
Best for: businesses standardizing on a non-Adobe editor.

### Nitro PDF — Familiar UI · Win · Mac · Standard $15/user/mo · Classic $270 (3-year)
Nitro's Microsoft-Office-style ribbon means teams learn it in minutes, and its batch conversion and Word output quality score near the top of our tests. E-signing is built in. Nitro PDF Standard is $15 per user per month billed annually ($180/yr), and Nitro PDF Classic is a $270 one-time, three-year Windows term licence (not perpetual); it's priced for businesses rather than individuals, but volume licensing and admin tooling justify it at team scale.
Best for: teams that want zero training time.

### Soda PDF Desktop — Web + desktop bundle · Windows · Subscription only
Soda PDF bundles its Windows desktop editor with the online tools reviewed above, so one purchase works on your PC and in any browser. Note that Soda's own FAQ now states it no longer sells a perpetual licence (checked October 22, 2026) — it is subscription-only, so compare the annual price against PDFelement and UPDF before buying.
Best for: deal-hunters who want desktop + web in one purchase.

### PDF Expert — Best on Mac · macOS · iOS · $79.99/yr · $139.99 lifetime
Readdle's PDF Expert is the most Mac-native PDF app there is — instant launch, buttery scrolling on huge files, clean conversion to Word and images, and tight iCloud/iPad handoff. A lifetime license is available alongside the subscription. Apple-only by design, which is exactly why Mac users love it.
Best for: Mac and iPad users who want native speed and polish.


## Best open-source PDF converters
### PdfCraft — New in 2026 · Rust · desktop + web (WASM) · MIT / Apache-2.0
Written from scratch in Rust by the ArtCraft team and open-sourced under MIT or Apache-2.0, PdfCraft is the most interesting PDF project of 2026: 17.5k GitHub stars within three weeks of its October launch, near-daily releases (v0.13.0 on October 23, 2026), native builds for Windows, macOS, Linux and FreeBSD, plus a WebAssembly build you can drop on any static host, a command-line tool and an opt-in MCP server for AI agents. 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. The project still calls itself alpha: editing existing text and non-Latin OCR are not there yet. (Not to be confused with the unrelated PDFCraftTool/pdfcraft, a Next.js web toolkit.)
Best for: a free, auditable Acrobat replacement for organising, merging and splitting PDFs offline.

### Stirling-PDF — Most tools · Self-hosted · Docker · Open-core
The heavyweight: 94.7k GitHub stars, 50+ tools (convert, merge, split, OCR, sign, redact, compress, watermark, automate — its pricing page says 60+) and a private API, v3.2.1 as of October 21, 2026, deployed with a single docker run on 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 is open-core (MIT core with proprietary modules): Free covers up to 5 users with 1,000 monthly automation credits, Team is a flat $99/month for 100 users, Enterprise is custom — the free 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 browser · 100% client-side · AGPL-3.0 · $79 commercial
A 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. Its site advertises 100+ tools (the documented reference lists 50+; v2.8.10 of October 19, 2026 is a security release, so self-hosters should update) 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 app · Linux · Windows · macOS · GPL-3.0
A 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 a Windows installer (macOS is build-from-source only; v1.14.0, May 2026), 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-PDF · Windows · macOS · Linux · MPL-2.0
The 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 pdf batch-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 CLI · Go · single binary · Apache-2.0
A 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 toolkit · C++ · every platform · Apache-2.0
The 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.

## Free vs paid
Decision guide
 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).

## Is it safe to use a PDF converter online?
Privacy & security
 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.

## How we rank
Why trust this page
 🧪 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 October 24, 2026 by reading each vendor's pricing page (or, where a page would not render, a dated 2026 third-party listing — the case for Soda PDF, Nitro, Smallpdf and EaseUS, whose own pages show no amounts). 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.

## FAQ
Q: What is the best PDF converter online in 2026?
A: 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.

Q: What is the best PDF converter online free of charge?
A: 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.

Q: Is it safe to convert PDF files online?
A: 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 .

Q: Can I convert PDF to Word online free without signing up?
A: 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.

Q: Do free online PDF converters add watermarks?
A: 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.

Q: What's the difference between a free and a paid PDF converter online?
A: 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.

Q: What is the best offline PDF converter for desktop?
A: 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.

Q: Can I convert a PDF without uploading it to a server?
A: 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.

Q: How do I convert a PDF without losing formatting?
A: 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.

Q: Why is PDF still the standard document format in 2026?
A: 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.

Q: Is the free converter on this page really private?
A: 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.

Q: Is there an open-source PDF converter online?
A: 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.

Q: What is the best PDF converter online with no upload?
A: 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.

Q: Can I convert TIFF to PDF, or PDF to TIFF, without uploading?
A: 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.

Q: Can I compress a PDF online without uploading it?
A: 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%.

Q: Can I sign, watermark or password-protect a PDF in the browser?
A: 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.

Q: Can I OCR a scanned PDF online for free without uploading it?
A: 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.

Q: Is there a free PDF reader online that does not upload my file?
A: 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.

Q: Can I convert a PDF to Markdown or HTML?
A: 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.

Q: Can I convert PDF to JPEG XL (JXL), or JXL to PDF, without uploading?
A: 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.

Q: Can I compress a photo to under 200 KB or 50 KB without uploading it?
A: 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.

Q: Is there a free passport photo maker that works offline?
A: 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.

Q: Can I scan documents to PDF with my phone camera without an app?
A: 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.

Q: Can I create or extract ZIP files, hash files or find duplicates in the browser?
A: 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.

Q: Can I fill a PDF form, redact or compare PDFs without uploading them?
A: 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.

Q: Can I convert Word, Excel or PowerPoint online without uploading?
A: 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.

Q: Can I automate a PDF workflow online without uploading — like compress, watermark and protect in one go?
A: Yes. The Workflow tool chains tools into one run: pick a preset (Scan to shareable PDF, Share safely, Print-ready, Archive scans) or add your own steps — Images to PDF first, Protect or any PDF-to-something converter last, anything else in between — set each step's options and press Run. Every file goes through every step on your device, and you can save the workflow in your browser (passwords excluded) to rerun it with one click. Self-hosted suites such as Stirling PDF sell this kind of automation in their paid tiers; here it is free and nothing is uploaded.

Q: Can I convert a PDF to an EPUB e-book, or check what is inside a PDF, without uploading it?
A: Yes. PDF to EPUB turns the text layer into a reflowable EPUB 3 with chapters (scans need OCR first), and EPUB to PDF prints an e-book to A5, A4 or Letter pages. Inspect PDF produces an eighteen-point preflight report — embedded fonts, image resolution, text layer, accessibility tags and language, JavaScript, attachments, encryption and whether earlier versions are recoverable — and Flatten PDF locks filled forms and strips comments. Summarise / ask gives you the key sentences with page numbers instantly, or — if you opt in to a one-time 350 MB download — a written summary from the open-source Qwen2.5 model running on your own device. All of them run in your browser; nothing is uploaded.

Q: Is there a command-line tool or an MCP server, so Claude or Cursor can work on my PDFs without uploading them?
A: Yes. pdfco is a free 2 MB tool from this site with twenty PDF tools — merge, split, rotate, page numbers, Bates, watermark, crop, resize, protect, unlock, metadata, flatten, repair, extract images, PDF to text, summarise, inspect — that runs on your own computer as a command-line tool and as an MCP server. Claude Desktop installs it with one double-click (a .mcpb bundle); Claude Code, Cursor and VS Code with one line or one click; any terminal with npx . Nothing is uploaded, no account, no licence to buy.

Q: PdfCraft vs Stirling-PDF vs BentoPDF: which should I use?
A: 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.
