Draw your signature or type your name in a handwriting font, then download it as a transparent PNG to use on any document. Nothing you create here is ever stored.
Once downloaded, your signature is a plain PNG image with a transparent background — you can drop it onto any document that has a logo upload field (like Invoice, Quote, Purchase Order, or Certificate), insert it into a Word or PDF document yourself, or print it out directly.
This creates an image of a signature for convenience — it isn't a legally binding electronic signature (an "e-signature" in the formal, audited sense). For contracts that need that level of verification, a dedicated e-signature service is the right tool.
