Remove a password or restrictions from a PDF

Bank statements and utility bills routinely arrive password-protected, which becomes tiresome when you need to read them regularly or combine them into one file for an application.

If you can open the document, this can save a copy without the password. A file that only restricts printing and copying — the so-called owner password — opens with no password at all, and this tool detects that and removes the limits without asking for anything.

That distinction is the useful thing to understand. A user password actually encrypts the file's contents, so it genuinely can't be read without it. An owner password leaves the contents unencrypted and merely asks readers to disable printing or copying, which is why removing it is a matter of rewriting a flag rather than breaking anything.

The practical case for this is mundane: statements that arrive protected with a password derived from your date of birth, which you then have to type every time you open them, and which can't be merged into a single file for an application until the protection is gone.

What this does — and what it doesn't

  • This is not a password cracker. To remove a password that stops the document opening, you need to know that password. We don't attempt to guess or break anything.
  • Only remove protection from documents you have the right to access.

Unlock PDF — frequently asked questions

Can this open a PDF if I don't know the password?
No. If the document requires a password to open, you have to supply it. What needs no password are files that only restrict printing, copying or editing: this tool detects them and removes the limits. Other tools here (merge, split, edit) also open such files directly.
What's the difference between the two kinds of PDF password?
A user password encrypts the document and is needed to open it. An owner password only sets permissions — printing, copying, editing — and the content isn't protected by it. The second kind is the one that can be lifted without knowing it.
My bank statement asks for a password every time. Can I save an open copy?
Yes, provided you know the password — enter it once and you can download a copy without it. This is the most common reason people need this, particularly when several protected statements have to be merged into one file for an application.
Can I process many PDFs at once?
Yes. Switch on "Process many files" to unlock up to 60 PDFs (300 MB in total) and download a ZIP. Files that only restrict printing or copying are unlocked straight away; a file that needs a password waits and asks for that file's password, and is left out if you don't give it. Files that were never protected are included unchanged.
Is my PDF uploaded anywhere?
No. Every operation runs in your browser using JavaScript and WebAssembly — the file never leaves your device. You can verify it: load the page, disconnect from the internet, and the tool still works. There is no upload endpoint to send it to.
