Is this a legally binding electronic signature?

In many jurisdictions, an electronic signature (including a drawn or typed signature on a PDF) is legally valid for most types of agreements under laws like the US ESIGN Act and EU eIDAS regulation. For higher legal assurance, consider using the Digital Sign PDF tool which adds cryptographic verification.

Can I sign on a tablet or phone?

Yes. The drawing tool works with touchscreens, making it easy to sign with your finger or stylus on tablets and smartphones. The signature quality is comparable to signing on paper with a stylus.

Is my signature stored anywhere?

Your signature is processed entirely in your browser. If you choose to save it for reuse, it is stored in your browser's local storage on your device. No signature data is ever uploaded to any server.

Can I place multiple signatures on one document?

Yes. You can add as many signatures, initials, and text fields as needed across any pages of the document. Each element can be positioned and sized independently.
