Signature Extractor
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.
Transparent signature PNG
Upload a signature on a light background
Works best with PNG, JPG, and WEBP signatures on white paper, scanned pages, or other light backgrounds.
Extraction controls
Adjust these controls when the paper tone is too visible, the source has soft shadows, or the signature strokes are very thin.
24
Higher values remove more paper tint, pale gray texture, and background noise.
58
Higher values keep thinner pen strokes, lighter ink, and softer edges.
24px
Controls the amount of empty transparent space around the extracted signature.

Tips
- White or light-background images produce the most stable transparent results.
- If thin strokes disappear, raise Stroke Preserve before reducing Paper Cleanup.
- If the image includes heavy shadows or perspective distortion, crop it tighter before upload.
Built for Signature Workflows
Tuned for contract screenshots, scanned sign-off pages, and white-paper signatures instead of general-purpose background removal.
Preserves Fine Strokes
Keeps lighter ink transitions, thin pen lines, and softer signature edges more reliably than aggressive paper cleanup.
Document-Ready PNG Export
Exports a cropped transparent PNG that is easy to place into PDFs, approval flows, templates, and documents.
