How to Remove Background from Signature

Digital signatures on documents, emails, and contracts look professional when they have a transparent background. If you've scanned or photographed your handwritten signature, it likely has a white paper background. RemoveBackgroundAI can make that background transparent so your signature overlays cleanly on any document.
