Protect PDF

Add password protection before sharing a PDF.

PDF and password

Add an unprotected PDF, enter and confirm a strong password, choose permissions, and download the protected copy.

About Protect PDF

Create a password-protected copy of a PDF. Keep the password separately from the file and test the exported document in the viewer your recipient uses.

Steps, and limitations

How to use it

  1. Open the PDF and enter the required password settings.
  2. Apply protection and download the new file.
  3. Close and reopen the output in a PDF viewer to verify access.

Things to know

  • There is no password recovery service. Keep a secure record of the password.
  • Viewer-enforced restrictions are not a substitute for controlling who receives the document.
