Troubleshooting
Common Sign PDF Problems
Am I allowed to process this PDF?
Use security tools only on documents you own or are explicitly authorized to modify, sign, unlock or disclose.
Why does another viewer behave differently?
Encryption, permissions, signatures and annotations are not handled identically by every PDF application.
Can the action be reversed?
Some security actions are intentionally difficult or impossible to undo. Preserve an authorized original before processing.

Reopen the file, test the intended restriction or signature, and inspect metadata and hidden content before delivery.
