How to remove a password from a PDF
Updated 3 June 2026
A password-protected PDF is either trivially unlockable or genuinely encrypted — and the difference comes down to which kind of password it has.
The two PDF passwords
- Owner (permissions) password — the PDF opens normally, but printing, copying or editing is blocked. This is the most common case, and it’s easy to remove.
- User (open) password — you’re prompted for a password before the file will even open. The contents are encrypted; you need the password to read it.
Removing PDF restrictions (you can open it, but can’t print/copy)
This is the “remove password protection from a PDF after opening” case. The permissions password can be removed without knowing it:
- Open the PDF unlocker.
- Drop your PDF in. It’s processed in your browser — nothing is uploaded.
- Download the unrestricted copy. Printing, copying and editing are back.
This works the same way Adobe Acrobat’s “remove security” does, except it runs locally and is free.
Unlocking a PDF that needs a password to open
If you have the password, the PDF unlocker will ask for it, decrypt the file, and save a clean copy with no password.
If you’ve forgotten it, no tool can simply strip it — the file is encrypted and the password has to be recovered by computation. Older PDFs and common, human-chosen passwords are very often recoverable. Request recovery and we’ll tell you if it’s possible and the price first — you only pay on success.
Is removing a PDF password legal?
Removing protection from your own PDF, or one you’re authorised to use, is a normal administrative task. Don’t use these tools on documents you’re not entitled to access.
