About Protect PDF

Add password protection and control what users can do with your PDF document.

  • User Password — required to open and view the document
  • Owner Password — controls permission settings (printing, copying, editing)
  • Permissions — fine-grained control over what actions are allowed

All processing happens locally in your browser using pdf-lib. No files are uploaded to any server.
