Frequently Asked Questions

Is this a legally valid electronic signature?

This tool adds a visual signature to your PDF. Legal validity of electronic signatures depends on your jurisdiction and the type of document. For legally binding e-signatures with audit trails, consider dedicated e-signature platforms like DocuSign or HelloSign.

Can I add multiple signatures to one document?

Yes. You can add your signature to multiple locations within the same PDF document.

Is my signature stored anywhere?

No. Your signature data is used only during the current session to generate the signed PDF. It is not saved on our servers.
