How to lock a PDF without a password: stop sharing, editing, copying, printing
How you can use Safeguard PDF Security to securely lock PDF files and control how they can be used.
1. Lock PDF files to devices so they cannot be shared.
2. Lock PDF files to locations to prevent use outside of certain environments (i.e. can be opened in the office only)
3. Prevent editing, copy & paste, printing and screenshots.
4. Automatically expire and revoke documents.
There are no passwords to enter, share or remove. Safeguard uses transparent and secure key management with licensing controls, AES encryption and DRM to ensure your PDF files are protected regardless of their location.
