FAQs
Is this a legally binding e-signature?
It places a visible signature image on the page, which is fine for most everyday agreements. It is not a cryptographic digital signature (PKI) and does not provide certificate-based identity verification.
Is my document uploaded anywhere?
No. The PDF is signed entirely in your browser — your document and signature never leave your device.
