Looking for a free digital signature? The terms often blend together, but there is a difference: a digital signature is the certificate-based kind, where cryptography ties the signer to the document. An electronic signature is the broader legal concept, recognized under the ESIGN Act, UETA and eIDAS for most everyday documents.
Signater's free plan gives you advanced electronic signatures — every envelope ships with a completion certificate and a full audit trail. Digital features, such as signing with the signer's own digital certificate, are available on the paid plans.
