Are e-signatures legally binding?

In most jurisdictions, a clear intent to sign (e.g. using this tool) is recognized as a valid electronic signature.

Is my signature data secure?

Yes. Signature creation and placement happen in your browser; nothing is sent to a server.

Legal value of electronic signatures?

In the EU (eIDAS) and US (ESIGN), electronic signatures that show intent to sign are legally valid for most contracts. For high-value or regulated documents, check local requirements.

Certificate-based digital signatures?

This tool adds a visible drawn or typed signature to the PDF. Certificate-based (PKI) signing for tamper evidence and identity verification would require a separate workflow and is not offered in-browser here.
