Create a digital signature
Signing a document digitally often needs an image of your signature. This tool lets you draw your signature with a mouse, finger or stylus and download it as a transparent image.
Why a drawn signature image helps
Many documents and forms ask for a signature as an image to insert, and the practical way to make one is to draw it, with a mouse, a finger on a touchscreen, or a stylus, and export it. Downloading it with a transparent background means it drops cleanly onto a document without a white box around it, looking like a real signature on the page. This is useful for signing PDFs, filling forms, and adding a signature to a design. Drawing in the browser keeps your signature on your machine rather than uploading it to a service, which matters for something as personal as a signature.
