About This Tool

Make your scanned signature look professionally digital. Phone photos of signatures often have gray, shadowy backgrounds that look bad on online forms. Our **Signature Cleaner** removes the paper texture and background, leaving only the clean ink strokes. It maximizes contrast and makes the background transparent or pure white so it blends perfectly into any application form.
