How to Unlock a Password-Protected PDF (When You Know the Password)

A PDF that asks for a password every time you open it gets old fast — especially if it's a document you password-protected yourself months ago and no longer need locked, or one you were sent that you need to open repeatedly without retyping the password each time. If you know the password, there's no reason to keep entering it.

This Unlocks, It Doesn't Crack

To be clear about what this tool does and doesn't do: QR Ivify's Unlock PDF removes password protection only when you already know and enter the correct password yourself. It has no password-cracking, guessing, or brute-force capability — if you don't know the password, this tool won't get you into the file. That's a deliberate limitation, not a missing feature.

Step by Step

1. Open Unlock PDF.
2. Drop in the password-protected PDF.
3. Type in the PDF's current password.
4. Click "Unlock PDF." Decryption happens entirely in your browser.
5. Download the unlocked copy — it opens without a password from now on.

How It Works

Decryption happens directly in your browser using a WebAssembly build of qpdf, a mature, widely-used PDF library — nothing is uploaded to a server at any point, including the password itself. If the password you enter is wrong, you'll see a clear message telling you to double-check it rather than a confusing error or a silently broken file.
