A registrar's desk for your PDFs — fill & sign, annotate, merge, split, crop, watermark, number, convert to images or text, compress, redact, and clean the metadata. Free, no upload, no account, no watermark.
🔒 Your document never leaves your browser — which matters most for exactly the documents this is for.
Drop a PDF hereor click to browse — forms, contracts, letters, scans
Pick a stamp, then click the page:
⚠ redaction box(es) placed. Applying flattens the document to images so the covered content is truly gone and can't be recovered — text becomes non-selectable.
Drag anything to reposition. Double-click text to edit it. For highlight/box/line/draw, drag on the page. Everything stays editable until you save.
Reorder ← →, rotate ⟳, crop ⛶, remove ✕ (click again to restore), tick pages to extract them into a new file. "Save PDF" applies everything.
Stamped diagonally across every page when you save.
Use {n} for the number and {total} for the page count. Applied when you save.
PDF → images
Each page downloads as an image. Big documents at 300 dpi can be large.
PDF → text
Pulls the selectable text out of the PDF. A scanned or image-only PDF has no text to extract — that needs OCR.
Compress
Rebuilds each page as a compact image — great for shrinking heavy scans and image-packed PDFs. Text becomes non-selectable, so keep it for sharing/printing, not further editing.
What this file says about itself — edit any value, save the changes, or strip it all. Author names and editing software often hide here:
Strip removes title, author, subject, keywords, creator, producer, and dates. This is metadata, not visible content — to black out content use the Highlight/Box tools or The Redactor.
Fill and sign a PDF without uploading it
Open the form, click where an answer goes, type. Click Signature, sign with your
mouse, finger, or stylus, and place it on the line. Add checkmarks and dates the same way,
drag anything into position, then save — the output is a normal flattened PDF ready to
email back. Think about what's in the PDFs people sign — leases, tax forms,
medical intake — and "we upload it to our servers to process it" stops sounding fine.
This page has no server, and works offline if you save it.
A whole PDF workshop, in five tabs
Fill & sign — type into real form fields (Form Desk finds them and puts a box on each), add text, checkmarks, dates and a drawn or uploaded signature, and annotate: highlight, boxes, lines, and freehand drawing. A Redact tool covers content in black and, on apply, flattens the page to an image so the covered content is genuinely gone — not just hidden.
Pages — every page as a card: reorder, rotate, crop, delete, append another PDF (merge), extract a selection, or split into one-file-per-page or custom ranges.
Stamp — a diagonal watermark and page numbers across the whole document.
Export — turn pages into images (PNG/JPG at your chosen resolution), pull the text out, or compress a heavy scan down to a compact file.
Metadata — read, edit, or strip the document's hidden self-description (author, creating software, dates) — the PDF companion to our Photo Cleaner.
Honest limitations
Everything except editing existing text is here — reflowing text already set in the PDF is the one thing no browser tool does honestly (even Acrobat locks it behind Pro), so Form Desk lets you cover or redact it and stamp new text on top instead.
Compressing and redacting rebuild the affected pages as images, so text there becomes non-selectable — that's the trade for a smaller file, and for redaction it's the point (the content can't be recovered).
Typed text uses the standard Helvetica font, which covers Western languages — other scripts aren't supported in text stamps yet.
This makes a signed-looking document, not a cryptographic e-signature. For "print, sign, scan, email back," it replaces the printer.
Password-protected PDFs need their password removed first, and scanned pages have no selectable text to extract (that would need OCR). Very large files render on your own machine, so they can be slow.
Tip: draw and save a reusable signature at Inkwell once, then upload the PNG here whenever a form needs signing.
