How to Remove a Password from a PDF (When You Know It)

To remove a password from a PDF you're authorized to open: open it in an Unlock PDF tool, enter the password once, and download an unlocked copy that opens freely from then on.

Steps

1. Add the protected PDF. Our tool processes it in your browser — the file and password never leave your device.
2. Enter the current password when prompted.
3. Download the unlocked PDF. No more password prompt.

The important limitation

This only works if you have the password. If a PDF is encrypted and you don't know the password, no legitimate tool can open it — the encryption is doing exactly what it's meant to do. Any service claiming to "crack" an unknown password is either lying, relying on the file being weakly protected, or doing something you don't want to be involved in. The right move is to ask the sender for the password or an unprotected version.

Two kinds of PDF password

• Open password: needed to view the document at all.
• Permissions password: lets you view but blocks printing, copying text, or editing.

Removing either one requires knowing that specific password.

Do this privately

Password-protected PDFs are usually protected for a reason — they contain something sensitive. That makes uploading one to a random server a poor idea. Use a tool that unlocks it locally in your browser. If you instead want to add protection, use Protect PDF.
