Why Are PDFs Password-Protected?

PDFs can be encrypted for several reasons:

  • Access Control: Only authorized users can open

  • Prevent Editing: Protect the content integrity

  • Disable Copy/Print: Avoid data leakage

But if you’re the rightful user and cannot access your file, you’ll need a tool that helps you unlock it safely without compromising security.
