This cleans the picture but doesn't resize it to a form's limits. Next step: the Signature Resizer.

What it does
- We find the signature and ignore the page edge, shadows and ruled lines.
- We correct uneven lighting, whiten the paper and strengthen the ink without changing its colour.
- Download it, or send it straight into the Signature Resizer to fit a form.
Examples
| You enter | You get |
|---|---|
| A phone photo with a shadow across the page | Clean dark ink on plain white, trimmed to the signature. |
| A signature on ruled paper | The lines are ignored; only the ink is kept. |
If it isn’t working
- It could not find a signature.
- Retake it on plain white paper in daylight, with a darker pen. Or drag the box around the signature yourself.
- Part of the signature is cut off.
- Drag the box larger: parts separated by big gaps can be treated as noise.
- The result is soft.
- The photo was small. A larger, sharper photo gives a sharper result.
