Free private PDF editor
Edit PDFs without uploading them — free, no account, no watermark.
Annotate, sign, reorder pages, merge, and export on this device. Up to 100 MiB and 250 pages during launch. Built for people who want a private browser PDF editor.
What you can do
A focused free PDF toolkit for everyday paperwork — with a hard privacy boundary: document bytes stay in the browser.
- Edit without uploading
Open a PDF on this device. Rendering and export run in your browser — not on our servers.
- Annotate and sign
Add text, highlights, ink, images, and visible signature marks. Fill supported form fields.
- Organize pages
Rotate, reorder, duplicate, or remove pages, then export a clean copy of the plan you see.
- Merge and protect
Combine PDFs locally, compress, extract pages, or password-protect an export when you need it.
- Free, no watermark
Free while we grow: full local editing without accounts, paid plans, or export watermarks.
- On-device PDF memory
Opened PDFs are stored in this browser by default for quick reopening. Turn this off or clear it anytime; draft recovery stays optional.
How it works
Three steps. No account wall. No document upload.
Open a PDF
Choose a file from your device. Nothing is sent to a document API.
Edit in the browser
Annotate, reorganize pages, merge, or mark text tools — all local to the tab.
Export a copy
Download a cleaned PDF. Your original file stays untouched on disk.
Built for AI agents, not just people
Automate private PDF work through the versioned browser API, or let compatible browsers discover metadata-only WebMCP tools. Document processing stays in the browser.

FAQ
Short answers about privacy, free access, and what the editor can do.
Does pdfmend upload my PDF?
No. Your PDF is opened and processed in your browser. pdfmend has no document upload API for editor content.
Is pdfmend free?
Yes. During launch pdfmend is free for everyone — no paid plans, no watermark, and no account required for editing and export (within published size and page limits).
Do I need an account to edit or export?
No. The free editor works without an account and exports without a watermark.
Where are recent documents stored?
Opened PDFs are stored by default in this browser’s IndexedDB, up to 25 files and about 200 MiB, so you can reopen them. Turn PDF storage off in Editor Settings to clear the library and preserve your opt-out. Draft recovery is separate and remains off by default. Nothing is uploaded.
What can I do in the free editor?
Add text, highlights, ink, images, and visible signatures; fill supported form fields; rotate, reorder, duplicate, or remove pages; merge PDFs; and export a clean PDF copy. Experimental Whiteout / cover draws an opaque visual cover and optional replacement; underlying content may remain recoverable. Experimental Delete text attempts verified removal for supported plain and CID-encoded text, then uses a clearly disclosed visual whiteout if exact deletion cannot be verified.
Is Whiteout / cover the same as redaction?
No. Whiteout / cover is a visual edit: it draws an opaque cover and optional replacement, while the underlying text may remain selectable or recoverable. Delete text (exp.) first attempts verified structural removal for supported plain and CID-encoded text. If exact deletion cannot be verified, it falls back to a visual whiteout and warns that the content may remain recoverable.
