Open a secured PDF document

By Cynthia, 14 November, 2025

If you receive a PDF that is protected by security features, you may need a password to open the document. Some protected documents have other restrictions that prevent you from printing, editing, copying, etc.

  • When opening a protected PDF, you will be prompted to enter the password.
  • When trying to copy or edit a secured PDF, you will be notified that you are prohibited to do it without the owner’s permission.
  • If you open a PDF that is encrypted by AIP feature of Foxit PDF Editor, please refer to AIP Protect.
