Online signature extractor for isolating handwritten signatures from white-paper scans, screenshots, and other light-background images into transparent PNG assets.
Built for scanned signatures and light-background handwriting. Remove the paper background, preserve thin strokes, and export a transparent PNG.
Extraction controls
Adjust these controls when the paper tone is too visible, the source has soft shadows, or the signature strokes are very thin.
Higher values remove more paper tint, pale gray texture, and background noise.
Higher values keep thinner pen strokes, lighter ink, and softer edges.
Controls the amount of empty transparent space around the extracted signature.
Waiting for an upload
Start by uploading a signature image on a white or light background.
The transparent result will appear here
After upload, the page will automatically extract and crop the signature.
