Is this a legal e-signature?

Omni PDF adds a visual signature to the document. Legal validity of e-signatures depends on your jurisdiction and the specific document. For legally binding workflows, check your local requirements.

Can I save my signature for later?

Yes — signatures you draw or upload are cached locally in your browser for the current session.
