Common questions
Frequently Asked Questions
What does signature verification check?
Certificate validity, signing authority, document integrity (whether the PDF was modified after signing), and timestamp verification.
Can I verify self-signed certificates?
Yes. Self-signed certificates are verified but flagged as not issued by a trusted Certificate Authority.
What if the document was modified after signing?
The tool clearly reports whether content was altered after the signature was applied — indicating the signature may be invalid.
Can I verify multiple signatures in one document?
Yes. All digital signatures in the PDF are verified individually, each with its own status report.
