What the AI can do with your PDFs

Each tool takes file paths and writes the result next to the input; the assistant sees where the file went and a one-line note. Ask things like "merge these three PDFs", "protect contract.pdf with a password and block copying", "what is inside invoice.pdf — any scripts or hidden metadata?" or "summarise the report and tell me what it says about pricing".

• merge — Combine two or more PDFs into one file, in the order given.
• split — Extract a page range into a new PDF, or split every page into its own file.
• rotate — Rotate all pages or the pages listed by 90, 180 or 270 degrees.
• delete-pages — Remove the pages listed and keep everything else.
• page-numbers — Number every page or a range, in the position and format you choose.
• bates — Sequential, zero-padded document numbers across one or many PDFs.
• watermark — CONFIDENTIAL, DRAFT or any text — diagonal, tiled, header or footer.
• add-text — Stamp a line or a few lines of text at a corner or the centre.
• crop — Cut a fixed margin from each side; nothing is re-rendered.
• resize-pages — Make every page A4, Letter, Legal, A5 or A3, content scaled and centred.
• nup — Two or four pages per sheet to save paper.
• protect — AES-256 password to open, and/or block printing and copying.
• unlock — Remove a password and restrictions from a PDF you have the password for.
• metadata — Set title, author, subject, keywords — or strip every trace before sharing.
• flatten — Burn filled form fields in and remove comments and markup.
• repair — Rebuild a damaged file with a clean structure.
• extract-images — Save the JPEG images embedded in a PDF as files.
• pdf-to-text — The text layer with paragraphs preserved, as .txt or .md.
• summarise — Key sentences ranked and cited by page, or the passages that answer a question.
• inspect — Eighteen checks: fonts, images, text layer, tags, language, scripts, attachments, metadata.

Rendering tools — OCR, PDF to Word/JPG/Excel/PowerPoint/EPUB, compress, sign, redact, grayscale and the workflow builder — stay in the browser toolkit, which also runs without upload.

Privacy, in one sentence

pdfco makes no network connections of its own: it reads the files you name, writes new files beside them, and every result ends with "Processed on this machine — 0 bytes uploaded." The engines are the open-source pdf-lib and pdf.js, bundled inside.
