About Unlock PDF
If you've got a password-protected PDF and you know the password, Unlock PDF removes the encryption so you can edit, compress, merge or share it without typing a password every time.
Important: we only remove passwords from PDFs you can already open. We never crack or brute-force unknown passwords — that would defeat the whole point of encryption.

Unlock PDF — frequently asked questions
Everything you need to know.
Can you remove the password if I've forgotten it?
No. We require the password to decrypt the file — that's how strong encryption is supposed to work. We never crack or brute-force PDFs.
Is my password sent anywhere?
It's sent encrypted (TLS 1.3) to the worker that decrypts your file, then immediately discarded. We don't log, store or transmit it anywhere else.
Will unlock work on any PDF?
Works on standard AES-128 and AES-256 encryption (PDF specification revisions 4 and 6). Older RC4 encryption also supported.
What if my PDF was protected with permission restrictions only?
Same path — supply the user (or owner) password and we'll strip every restriction.
Can I re-add the password later?
Yes — use our Protect PDF tool to encrypt it again, potentially with a new password.
