Frequently asked questions
Is this certificate-based digital signing?
No. This places a visual electronic signature only. It does not verify identity or provide a certificate, audit trail or universal legal guarantee. Modifying a digitally signed PDF can invalidate earlier signatures.
Is my signature saved online?
No. Document and signature content stay in browser memory until cleared or the page closes. Only your downloaded copy is saved.
