How to Unlock a Password-Protected PDF You Own
If a PDF asks for a password every time you open it — and you already know that password — you can remove the lock so the file opens freely. This guide is for documents you own or are authorised to access; here’s how to unlock one.
How to unlock a PDF
- Open the Unlock PDF tool and choose your file.
- Enter the password you already have for it.
- Press Unlock and download the unrestricted PDF.
A note on permission
This tool is for files you’re allowed to open — your own documents, or ones you’ve been given access to. It asks for the existing password because it removes a lock you can already get past, not one you can’t. If you’ve forgotten the password to your own file, there’s no way to recover it; you’d need to get it from wherever the file came from.
The opposite job: adding protection
Want to lock a document instead? Protect PDF adds a password so only people you share it with can open it.
Tips
- Everything stays on your device. The unlock happens in your browser, so neither the file nor the password is uploaded.
- Keep the password safe if you ever need to re-protect the file.
Frequently asked questions
Do I need the password? Yes — this is for files you can already open and are permitted to use.
