Signature Background Remover (Transparent PNG)

Make the paper disappear and keep only the ink. The result is a transparent PNG you can place on documents.

Your file is processed on your device. Nothing is uploaded.

This uses a simple colour-based method, not AI. It works best on dark ink and plain white paper. Shadows or lined paper can leave marks. For a KB or size target, use the Signature Resizer after this.

How to use

  1. Take a photo of your signature on plain white paper in good light.
  2. Choose the photo.
  3. Move the slider until thin strokes stay and the paper is gone.
  4. Download the transparent PNG.
