Frequently Asked Questions

3 questions answered

What's the difference between user and owner PDF passwords?

A user password (open password) prevents anyone from opening the PDF without the password. An owner password (permissions password) allows opening but restricts printing, copying, or editing. The password remover can remove owner passwords without any password; user passwords require you to know the password first.

Can I remove a PDF password I don't know?

If the PDF has an open (user) password you don't know, the PDF is encrypted and cannot be unlocked without the password. If the PDF has only owner restrictions (you can open it but can't print or edit), those restrictions can be removed without any password.

Is it legal to remove a PDF password?

Removing a password from a PDF you legitimately own or have permission to access is legal in most jurisdictions. Removing passwords from commercially DRM-protected content (e-books, premium reports) may violate terms of service or copyright law.
