How do I get the best result?

Use a dark pen (black or blue) on plain white paper, take the photo in good light with the paper flat, and keep the signature fairly large in the frame. Then use "Auto set ink strength" and adjust the slider if needed.

What is the difference between PNG and JPG?

PNG keeps a transparent background, so you can place the signature on top of a document or a PDF. JPG has a white background, which is what most upload forms want.

The signature looks broken or too thin. What should I do?

Raise the ink strength a little and lower the edge softness. If the photo has a shadow across the paper, make sure "Even out shadows" is ticked.

Is my signature uploaded or stored?

No. The picture is processed inside your browser and never sent to any server.

Can I use this signature legally?

It is an image of your handwritten signature, fine for forms, letters and resumes. A legally binding digital signature on contracts needs a proper e-sign service, which this tool is not.
