Sign PDF
Sign yourself or invite others, with a verifiable record of every action.
Legally binding e-signatures with an audit trail.
Sign PDF turns any document into a signable file in seconds. Drop signature, initial, date, and text fields onto the page, sign yourself, or route the document to one or more signers in order. Every action — view, sign, decline — is timestamped into an audit certificate so the resulting PDF is legally binding under ESIGN and eIDAS.
