# Resize Signature to 10 KB

ToolSugar takes a photo or scan of your signature, turns grey paper white, darkens the ink, and saves a JPG at or under 10 KB, or 10000 bytes. Plain signatures on a clean background compress very well, so they usually stay readable at this limit. Everything runs in your browser, so your signature is never uploaded.

Runs on your device

## How it works

1. Sign on plain white paper in dark ink and take a straight, well-lit photo or scan.
2. Add the image. Crop it close first if your form wants a tight signature.
3. Leave the white paper switch on so shadows and grey paper are cleaned up.
4. Press Resize, look at the preview, and download the JPG.

## Key facts

- **Target**: At or under 10 KB, counted as 10000 bytes
- **Paper cleanup**: Turns paper white and darkens ink, keeping blue ink blue
- **Where it runs**: In your browser, so your signature is never uploaded

## Common uses

- Upload a signature to a tight 10 KB government form.
- Replace a dim phone photo of your signature with a cleaner copy.
- Prepare a signature for an exam application.

## Questions

### My signature looks faint at 10 KB. How do I fix it?

Sign with a thicker dark pen, and crop close to the ink. A tight crop leaves fewer pixels to store, so the tool has less need to reduce the picture and thin strokes stay visible.

### How does the paper cleanup work?

It reads the brightness of your image, treats the most common level as paper, then stretches contrast so paper reaches pure white and ink gets darker. Turn the switch off to keep the original tones.

### Is my signature sent to a server?

No. Decoding, cleanup and encoding all happen in your browser tab, and nothing is uploaded. Closing the tab clears the image from the page.
