What format is the signature?

A PNG with a transparent background, so it sits cleanly on any form, contract, or PDF.

Is my signature uploaded?

No. It is drawn and exported entirely in your browser. Nothing is sent to a server.

Can I sign with my finger on a phone?

Yes. The pad supports touch, mouse, and trackpad input.

How do I add it to a PDF?

Download the PNG, then use a PDF tool that lets you insert an image — for example, FileKit’s PDF Sign tool.

Can I change the pen color?

Yes — choose black, blue, red, or any custom color before signing.

What if I make a mistake?

Click Clear to wipe the pad and start over.

Is a drawn signature legally valid?

In many places an electronic signature is valid, but rules vary by country and document. Check the requirements for your specific use.

Will the background be white?

No — the background is transparent, so only your signature strokes appear when placed on a document.
