Frequently Asked Questions
How do I make my signature transparent?
Take a photo of your signature written on plain white paper. Upload it here, adjust the threshold slider if needed, and download the result as a transparent PNG.
Why is the slider needed?
Lighting conditions in photos vary. The slider sets the 'threshold' between what is considered background (made transparent) and what is considered ink (made pure black).
Is my signature secure?
Yes. Your signature photo is processed 100% locally in your web browser. It is never uploaded to any server, ensuring complete privacy.
