# Resize Image to 20 KB

ToolSugar reduces a photo to at or under 20 KB, or 20000 bytes, in your browser. Many exam and job forms use limits around this size for applicant photos. The tool tries lower JPG quality first, then smaller dimensions if needed, and reports the final width and height. Your file is not uploaded.

Runs on your device

## How it works

1. Add one JPG, PNG, WebP or HEIC image.
2. Check that the target says 20 KB, or type a different limit.
3. Press Resize and let the tool search for the best quality that fits.
4. Read the size and dimensions on the result, then download it.

## Key facts

- **Target**: At or under 20 KB, counted as 20000 bytes
- **Output**: JPG by default, with PNG and WebP available
- **Where it runs**: In your browser, with no upload

## Common uses

- Upload an applicant photo to an exam registration form.
- Attach a small headshot to an online job application.
- Bring a scanned ID image under a portal's limit.

## Questions

### My form says between 10 KB and 20 KB. Will this work?

Usually, because the tool aims for the highest quality under 20 KB, so results tend to land close to the limit. Very simple images can come out smaller, so check the size shown on the result.

### Will the file really be under the limit?

Yes. The tool measures every encoded attempt in bytes and only returns one at or below 20000 bytes. If nothing usable fits, you get an error instead of an oversized file.

### Does it change the width and height?

Only when it has to. It lowers JPG or WebP quality first, and the picture shrinks only if quality alone cannot reach the target. The result shows the final dimensions.
