Unlock PDF
Remove usage restrictions from a PDF free — strip owner-password locks that block printing, copying or editing, and save an unrestricted copy. Private.
About the Unlock PDF
Many "locked" PDFs open perfectly but block printing, copying or editing with an owner (permissions) password. This tool removes those restrictions in your browser: it opens the document, drops the permission flags and saves a clean, unrestricted copy you can use freely.
We're honest about the limits. A PDF that demands a password just to open it uses full content encryption, which cannot be undone by a browser-only tool — if you have that kind of file, open it in a desktop reader with the correct password first, then re-save or print it to a new PDF. This tool detects that case and tells you clearly.
Only unlock documents you own or have permission to use. Everything runs locally with pdf-lib, so your file is never uploaded, and there are no watermarks or sign-ups.

Frequently Asked Questions
Will this open a PDF that needs a password just to view it?
No. A password required to open a file means the content is encrypted, and that can't be removed in a browser. Open it in Adobe Acrobat, Preview or another desktop reader with the correct password, then re-save or print it to a fresh PDF. The tool will tell you when it detects this type of protection.
What kind of lock can it remove?
It removes owner-password restrictions — the permission flags that stop you printing, copying text or editing a PDF that otherwise opens normally. After processing, the saved copy has those restrictions cleared.
Is it legal to unlock a PDF?
Only unlock documents you own or are authorised to modify. Removing restrictions from someone else's protected file without permission may breach copyright or the document owner's terms — this tool is intended for your own files.
Is my PDF uploaded?
No. The file is processed entirely in your browser with pdf-lib and never sent to a server, keeping it private.
