PDF Workspace
Lock a PDF behind a password before you send it.

Before a sensitive document leaves your hands, it should need a password to open. Protect PDF adds password encryption to any file, so only someone with the password you set can view it — useful for payslips, contracts, medical records, or anything you are emailing rather than handing over in person. Set the password once, and every copy of the file stays protected until the recipient enters it.
