PDF Tools

Stamp your logo or an image watermark on PDF pages — choose position, size, transparency and which pages.

Number the pages of a PDF — choose position, format (1, Page 1 of 10), starting number, font size and which pages. Runs in your browser.

Compare two PDFs (or Word files) and see exactly what text was added, removed or changed — page by page, highlighted like a redline.

Shrink a PDF for email or upload. Pick light (keeps text selectable) or stronger image-based compression.

Trim the margins of PDF pages — set how much to cut from each side, on all pages or a selection — to remove white space or scanner borders.

Click the pages you don't want and download the PDF without them. Everything stays on your device.

Automatically straighten crooked scanned pages and whiten the paper background — fix tilted scans, remove gray noise and shrink the file with grayscale. Runs in your browser.

Add text, white-out boxes, highlights, rectangles and form fields to PDF pages — click to place, drag to move — then download.

Send a PDF for signature to several people: place signature boxes for each signer, then everyone signs in turn in their browser. When the last person signs, a signing certificate with an audit trail and SHA-256 fingerprints is added. No account, nothing uploaded.

Save every picture embedded in a PDF as PNG or JPG files — at their original resolution — downloaded together as a ZIP.

Fill in PDF forms online — text fields, checkboxes, dropdowns and radio buttons are listed for you to complete — then save or flatten the result.

Flatten a filled PDF form so the answers become part of the page and can't be edited — ready to email, print or archive.

Add photos, scans or diagrams to an existing PDF as new pages, placed exactly where you want them.

Check your book's interior PDF against Amazon KDP paperback rules before uploading — trim size, bleed, page count, gutter and outside margins, embedded fonts — and get your cover's spine width.

Join several PDFs into a single document in the order you choose. Files never leave your device.

Recognize the text in scanned PDFs and create a searchable PDF you can select and copy from — or extract the text — in 100+ languages.

Rearrange PDF pages — move pages, rotate, duplicate or delete them — with thumbnails, then download the reorganized PDF.

Rearrange a PDF into booklet order — two pages per sheet side, ready to print double-sided, fold and staple — with blank pages added automatically.

Add clickable bookmarks (an outline / table of contents) to any PDF — nested chapters and sections, or auto-suggested from each page — so readers can jump around in any PDF viewer.

View and edit a PDF's hidden properties — title, author, subject, keywords, creator, producer and dates — or wipe them before sharing.

Count the pages in one or many PDFs at once — with page sizes, orientation and a total — handy for printing quotes and batch jobs.

Convert PDF to PDF/A-2b or PDF/A-3b for long-term archiving — adds XMP metadata and an sRGB color profile, removes JavaScript and other forbidden features, and checks fonts. Runs in your browser.

Extract the text from a PDF as plain text or Markdown — keeping lines and paragraphs, with headings detected — to copy, search or reuse.

Lock a PDF with a password using AES-256 encryption. The password and file never leave your browser.

Permanently black out sensitive text and images in a PDF — the redacted pages are re-rendered so the hidden content is truly gone.

Try to recover a damaged or corrupt PDF — rebuild its structure, or as a last resort re-render readable pages into a new PDF.

Turn every page, or just the ones you choose, by 90°, 180° or 270° and save the fixed PDF.

Use your phone or laptop camera to scan documents into a clean PDF — capture several pages, enhance for readability, reorder and save.

Sign a PDF in your browser — draw or type your signature (or upload an image), place it on any page, and download the signed PDF.

Break a PDF into separate files — every page on its own, by page ranges, or just the pages you pick.

Remove the password from a PDF you have access to — enter the password once and download a copy that opens without it.
