Unlock PDF
Remove password protection from a PDF you already have the password for.
About this tool
Removes password protection from a PDF you already have the password for — enter the correct password once, and download a copy with no password required to open it. Useful for a PDF you legitimately own but are tired of re-typing the password on, before archiving or sharing it further.
Decryption happens entirely in your browser using the open-source pdf-lib library; your file and password are never uploaded anywhere.
Frequently asked questions
- I don't know the password — can this crack it?
- No. This tool only removes protection from a PDF once you supply the correct existing password — it doesn't attempt to guess, brute-force, or bypass an unknown password. Use it only on files you're authorized to open.
- What if the password is wrong?
- The file will fail to decrypt and you'll see an error — double-check for typos, extra spaces, or the wrong password entirely (the owner and user passwords set on a PDF can differ).
- Is my PDF or password uploaded anywhere?
- No — decryption happens entirely on your device. Nothing is sent to any server.
