How to Remove a Password From a PDF

Password-protected PDFs are useful right up until the password becomes an obstacle to your own workflow — having to re-enter it every time you open a file you reference often, for instance. If you know the password and just want it gone, here's how.

Before you start: you need to know the password

This removes a password you already have — it doesn't crack, guess, or bypass one you've lost. If you don't know the password, there's no legitimate way to get past real PDF encryption without it; that's what makes it real protection in the first place.

How to remove a password

1. Open Remove Password.
2. Drop in the protected PDF.
3. Enter the current password.
4. Download the unlocked file.

If the password is entered incorrectly, you'll get a clear error rather than a broken file — try again with the correct password.

What kinds of protected PDFs this handles

Standard PDF password encryption comes in a few generations — older 40 and 128-bit RC4 encryption, and newer 128-bit AES encryption, all of which are handled. The newest standard, 256-bit AES (part of PDF 2.0), isn't supported yet — if a file uses that and won't unlock, that's the likely reason.

After removing the password

Once unlocked, the file behaves like any normal PDF — it opens without a prompt, and you can run it through other tools freely. If you're preparing a file to share more broadly after removing its password, consider whether it needs a lighter form of protection instead: Flatten PDF locks in form field values without requiring a password at all, which is often what people actually want when they're tempted to leave old protection in place just to stop accidental edits.

FAQ

Is my password sent anywhere to check it? No — the password is checked and used to decrypt the file entirely within your browser; it's never transmitted.

Can I remove protection from multiple files in one batch? Not currently — each file needs to be processed individually, particularly since different files may use different passwords.

What if I want to keep some protection, just change the password? Remove the old password first, then use Encrypt PDF to add a new one — there's no direct "change password" step, but the two together achieve the same result.
