Unlock a PDF you have the password for

Remove the password from a PDF you can already open. Runs in your browser — your password never leaves your device.

Files are processed entirely in your browser. Nothing is uploaded to any server.

About this tool

A password-protected PDF is useful when the document is in transit, but can become an inconvenience once it has reached the right hands. Opening the same file repeatedly means typing the password every time, and many services that accept PDF uploads refuse password-protected files outright. Unlock PDF removes the password from a PDF you already know the password for, producing a clean copy you can open freely.

The tool works on user-open passwords — the kind you type to open the file. It also removes owner restrictions such as printing, copying, and editing bans, since those restrictions are tied to the same password credential. To use it, upload the protected PDF, type the password, and download the unlocked result. If the password is wrong, you will be told immediately.

The file and the password are processed entirely within your browser using a WebAssembly build of the qpdf library. Neither the password nor any byte of the file is sent to any server. This also means the tool will not help with files whose passwords you do not know — it does not attempt to crack or brute-force anything.

Frequently asked questions

Can you crack a forgotten password?
No, and we wouldn't — this tool only re-saves a PDF you can already open.
Does this also remove printing/copy restrictions?
Yes, owner restrictions are removed when you have the open password.
Is my password sent anywhere?
No. Both the file and the password are handled entirely in your browser.
What about certificate-encrypted PDFs?
Those require the private key/certificate, which we can't process in a generic web tool.
Works offline?
Yes, after first load.
