Unlock PDF
Remove password protection from a PDF document.
Overview
The Unlock PDF tool removes password protection from a PDF file. If a PDF is secured with a password that restricts opening, printing, copying, or editing, this tool can remove those restrictions — provided you know the correct password.
Info
You must know the document's password to unlock it. This tool cannot bypass or crack unknown passwords.

Options
| Option | Description | Required |
|---|---|---|
| Owner Password | The master password that controls permissions on the PDF (printing, copying, editing restrictions). | Yes |

| Output File Name | The name for the unlocked PDF file. | Yes |
Tips & Notes
Tip
If a PDF only has permission restrictions (e.g., no printing allowed) but no open password,
you only need the owner password. If the PDF has both an open password and an owner password,
enter both to fully unlock the document.
Warning
The unlocked PDF will have all password protection and permission restrictions removed.
Anyone with the file will be able to open, print, copy, and edit it.
