Protect PDF

Add password protection to a PDF file

Keep your PDF documents secure with password protection. Add a user password that is required to open the file, and optionally set a separate owner password to restrict editing and printing. Perfect for confidential documents, contracts, and personal files.

Password Options

  • User Password: Required to open and view the PDF. Anyone who has this password can read the document.
  • Owner Password: Controls editing, printing, and copying permissions. If left empty, the user password is used for both.

Tips for Strong Passwords

  • Use at least 8 characters with a mix of letters, numbers, and symbols
  • Avoid common words or personal information
  • Store your passwords securely — password recovery is not possible
  • To remove protection later, use our Unlock PDF tool
