Check a signed PDF
See in a few seconds whether a document signed with PenlyDoc is exactly as it was when everyone signed it.
What the check tells you
Not changed
Every signed PDF carries a digital seal. If even one letter changed after signing, the seal no longer matches.
Who and when
The last page of the PDF is the certificate of completion: who signed, when, and from which device.
Your PDF reader says “validity unknown”?
Some PDF readers show this for seals whose certificate is not on their own list. The document is still protected: if it had been changed, the reader would say so. The check on this page gives the answer.
From this service
If the document was completed in PenlyDoc, the check also finds its record here and shows when it was completed.
