Resize Image to 20 KB

Some forms only allow tiny files. This tool shrinks your photo or signature to under 20 KB as a JPEG, keeping it as clear as the limit allows. Free and private.

Make your image smaller than 20 KB

A 20 KB limit is common for signatures and small photographs on exam, scholarship and government forms. To get that small, the tool lowers JPEG quality and, if needed, reduces the pixel dimensions, then keeps the clearest version that fits.

How it works

  1. Upload your image — drop one or more photos or scans into the box above. JPG, PNG and WEBP are accepted.
  2. Pick your target size — the first option is selected for you.
  3. Resize and download — the tool finds the best quality that fits. One file downloads as a JPEG; several download together as a ZIP.

Common uses

Getting the clearest result at 20 KB

Crop away everything except the face or the signature before resizing. Use a plain, light background and good lighting. A smaller, tightly cropped image stays much sharper at 20 KB than a large photo squeezed down.

Frequently asked questions

How do I resize a photo to 20 KB?

Upload it, keep “Under 20 KB” selected and click Resize Image. The tool lowers quality and, if needed, the dimensions until the JPEG is under 20 KB.

The form needs 10 KB to 20 KB. What should I pick?

Choose “10–20 KB”. The tool keeps the file inside that range.

Why is my 20 KB photo smaller in size on screen?

A clear photo needs more data than 20 KB at full phone resolution, so the tool reduces the pixel size as well. This is normal and forms expect it.

Is it safe to use?

Yes. Your image is processed in your browser and never uploaded.
