Unlock PDF

Remove a password from a PDF you can open — free & in-browser.

Remove the password and open restrictions from a PDF you already have the password for, so you no longer have to type it every time. Just upload the file, enter the current password, and download a clean, unprotected copy. Decryption happens entirely in your browser with @cantoo/pdf-lib — the file and password never leave your device, and there's no sign-up or watermark. Only unlock documents you own or are authorised to modify; this tool can't crack unknown passwords.
