Unlock a PDF

Unlock a PDF is a free tool that runs entirely in your browser, with no data ever sent to a server. Remove password protection from a document, provided you know it.

What it's for

Regain password-free access to a document you protected yourself, or received along with its password, to edit it or merge it more easily with other tools.

What this tool does not do

This tool does not crack or guess an unknown password: it only removes a protection when you supply the exact password.

Frequently asked questions

Can this tool remove a password I don't know?

No. It removes an existing protection only if you provide the correct password: this is not a password-cracking tool.

What types of protection are supported?

AES-256 and RC4 (128 and 40-bit) encryption, the two standards used by almost all password-protected PDFs.

Are my files sent to a server?

No: processing happens entirely in your browser, on your device. No file is ever transmitted to a server, at any point.
