Removing a password from a PDF you already know the password for produces a clean, unencrypted copy — useful once you no longer need the file locked, or before merging or editing it, since most PDF tools can't open an encrypted file's pages directly.
Steps
- Open Unlock PDF and upload the protected file.
- Enter the current password.
- Run it and download the unencrypted copy.
What actually happens
Given the correct password, the same WebAssembly build of qpdf used by Protect PDF decrypts the file entirely in your browser and hands back a genuine unencrypted copy — nothing is transmitted anywhere. A wrong password fails cleanly with a clear error, rather than producing a corrupted or partial file.
A couple of things worth knowing
- This isn't a password cracker — it removes protection using a password you already know, not one you've lost. If you've genuinely forgotten the password to your own file, this tool can't recover it; there's no shortcut around real encryption.
- It also strips owner-level restrictions (printing/editing locks) along with the open password, not just the open password alone.
- Once unlocked, the file can go straight into any other PDF tool on this site — Merge PDF, Compress PDF, and the rest — since none of them can read an encrypted file's pages directly.
