How to save a PDF as read only so it cannot be edited, copied, or printed, without using passwords
How to make a PDF read only permanently so it cannot be edited, printed, saved as another file format, copied, unprotected, or shared.
Safeguard PDF Security enables you to protect a PDF as read only. There are no passwords for users to remove or share, and PDF restrictions are enforced in the secure PDF Viewer so users cannot remove them.
As well as making a PDF read only, you can add expiry, apply dynamic watermarks to identify users, stop screenshots, and lock use to devices and locations.
