How to use this PDF tool

  2. Enter the current password when required. To protect a file, enter and confirm a new password.
  3. Process the document and download the resulting PDF.

Before you begin

Unlocking requires the password when the document needs one; this tool doesn’t recover forgotten passwords. Keep any new password somewhere safe.
