Compress an image to 20 KB
To compress an image to 20 KB, drop it in: the tool is already set to 20 KB. It lowers the quality and, if it has to, the pixel size until the file fits, then shows the result. Nothing is uploaded.

How it works
- Drop your picture into the box above.
- The size is set to 20 KB. Change it if your limit is different.
- Check the result and download it.
When do you need 20 KB?
A 20 KB limit is common for signatures and small photo fields on application forms.
What 20 KB means for a photo
A 12-megapixel phone photo is 3 to 6 MB, so 20 KB is a big reduction. At this size a picture about 370 pixels wide keeps good quality; much larger than that and the tool has to compress harder, which shows as blur and blocks.
Tips
- Crop to what you need first: fewer pixels mean a smaller file at the same quality.
- Start from the original photo, not a copy sent over a chat app.
- If the form also needs exact pixels (for example 200 × 230), use the exam page for that form.
Questions people ask
How do I compress an image to 20 KB?
Drop it in the tool above, which is set to 20 KB, and download the result.
Will the picture look worse at 20 KB?
A little: 20 KB is much smaller than a camera photo. Cropping and shrinking the pixels first keeps it looking clean.
Why do some sites count 20 KB differently?
Some systems count 1 KB as 1000 bytes and others as 1024. To be safe, aim a little under the limit. The exam and size pages land inside an exact window.
Is it free?
Yes. No signup, no watermark, and no limit on how many pictures you compress.
Is my picture uploaded?
No. Compression happens in your browser, so the picture never leaves your device.
