Unlock PDF — Remove a Known Password Without Uploading

About Unlock PDF

The PDF Unlock tool removes the password from a PDF you can already open, producing a copy that opens freely without prompting. You supply the file and its current password, and the tool returns unlocked.pdf with the protection stripped out. It is meant for the everyday situation where you have a legitimate, password-protected document — a bank statement, an invoice, a report you created — and you are tired of typing the password every time, or you need to combine it with other files in a tool that cannot handle encryption.

Unlocking is handled by qpdf, the same open-source library used for protection, compiled to WebAssembly and run inside the browser. You provide the password that the PDF currently uses; the tool decrypts the file with it and writes out an unencrypted version. This is decryption with the correct key, not password cracking — it only works when you already know the password and can therefore open the document yourself. If the password is wrong, the operation fails and the tool tells you the password may be incorrect rather than producing a broken file.

Doing this locally matters for the same reason it does when protecting a file. Removing a password on a server would mean uploading a document you considered sensitive enough to encrypt in the first place. Here the qpdf engine reads, decrypts, and rewrites the file entirely on your device, so the unprotected copy is created without the original ever leaving your browser. The result downloads immediately once the password is accepted.

Use this only for documents you are entitled to open. The tool deliberately requires the existing password — it is not a way around protection you do not have the key for, and it cannot recover or guess a forgotten password. Once unlocked, treat the output as you would any unprotected file: it no longer asks for a password, so store and share it accordingly, and re-protect it with the Protect tool if you still need it encrypted.
