How small does it need to be?

Your result is saved as a JPG, the format almost every upload form accepts. We search for the best quality that fits your limit, and only shrink the dimensions if quality alone can't get there.

Why 20KB is the toughest common limit

A phone photo is often 3–8 MB, so reaching 20KB means shrinking the file by more than 99%. That is only possible with a small picture, so pixel dimensions matter more here than on larger limits.

What helps most

Crop away everything except the face or the signature, use a plain light background and avoid fine patterns. Smooth areas compress far better than detail, and fewer pixels mean fewer bytes.

Step by step for 20KB

Crop tightly around the face or signature.
If the form lists pixel dimensions, set them first with the image resizer.
Compress here with “Under 20KB” selected.
Zoom the result to 100% and check the face or ink is still clear.
If the portal still refuses it, try a custom 18KB, since some systems count kilobytes differently.

Frequently asked questions

How do I resize an image to 20KB?

Add your image, leave “Under 20KB” selected and press Compress. Download the result when it finishes.

Does resizing reduce quality?

Slightly. The tool keeps the highest quality that still fits your limit, so you only lose what is needed.

Is it private?

Yes. Processing happens in your browser and nothing is uploaded.

Why does my signature look pale after resizing to 20KB?

Faint ink loses detail first when a file gets very small. Sign with a dark pen on white paper in bright, even light, and crop tightly before compressing.

Can a color photo really fit in 20KB?

Yes, if the picture is small and the background is plain. A full-size photo cannot, which is why the tool reduces pixel dimensions when quality alone is not enough. If it cannot reach 20KB without a heavy drop in quality, it tells you.
