Free signature background remover

Turn a handwritten signature on paper into a transparent PNG directly in your browser. Use your camera, clean the paper background, then download or copy the finished signature image.

How it works

Capture

Place your handwritten signature inside the guide box and capture a frame from your phone or desktop camera.

Remove the white paper background

The app crops the guide area and converts the signature strokes into a black-on-transparent PNG.

Download a transparent PNG

Save the finished signature image for Word documents, PDFs, forms, and document overlays.

No upload

Signature images are processed locally in your browser. The app does not ask for an account and does not upload your signature.
