Frequently Asked Questions
Can an electronically signed PDF be changed?
A PDF file can sometimes be edited, but a properly sealed e-signature packet should show evidence that the document was changed after completion.
What should I check to verify a signed document?
Check the final PDF, completion certificate, signer timestamps, document hash or seal status if available, and whether the platform marks the file as altered.
Do I need digital certificates for tamper evidence?
Digital certificates can strengthen tamper evidence, but many business workflows can rely on reputable platform audit trails and sealed completion packets.
