Signature Extractor Free Online: Scan Signature to PNG
Extract handwritten signatures from scans or photos and export transparent PNG signatures for forms, proposals, and approvals.
Signature Extractor is useful when a paper signature needs to become a reusable digital asset without carrying the full paper background with it. It helps convert handwritten signatures into lightweight transparent graphics for document workflows.
How to Use It
- Upload your document image and wait for the local preview to load.
- Adjust the settings: Crop the signature area, choose trim padding and ink style, then export the cleaned signature as a transparent PNG.
- Download the result: Download the processed file directly to your device.
Controls and Options
Crop tightly around the signature first, then increase trim padding only enough to keep the strokes from touching the edge.
Formats and Output
Input: JPG, PNG, WebP. Output: transparent PNG. The extracted signature is trimmed and prepared for reuse on forms and approvals.
