Is this PDF signed?
Choose a PDF. The inspector reads it in this browser and reports whether a digital signature is present, the certificate subject and expiry when they are there, and the signature fields on the page. An EndorsedSign seal is reported on its own, because that seal is drawn onto the page and does not carry a PDF certificate or byte range. No account required.
Not legal advice. This reading is not a validity opinion. It does not prove who signed, that the signature is intact, or that a court will accept the document.
