Reduce image size to 20 KB

Many government and exam forms in India accept a scanned signature of only 10–20 KB. Phone photos are usually 2–5 MB, so the form rejects them.

This tool shrinks your image to 20 KB or less right in your browser. It lowers the JPEG quality step by step and, only if needed, reduces the pixel size, so the result stays as clear as possible.

Commonly needed for signatures on SSC, railway (RRB), bank (IBPS, SBI) and many state government forms.

How to compress an image to 20 KB

  1. Choose your photo or scan. JPG, PNG and WebP all work.
  2. The target is already set to 20 KB, so the tool compresses it straight away.
  3. Check the Before and After preview and the new size.
  4. Tap Download to save your image.

Tips for the best result

  • Crop the signature tightly before compressing, so the KB go into the ink and not the empty paper.
  • Sign with a black or dark blue pen on plain white paper for the sharpest result.
  • Check the exact limits in your notification. Many forms also ask for a minimum size, like 10 KB.

Frequently asked questions

How do I reduce a signature to 20 KB?

Choose the image here. The target is already set to 20 KB, so the tool compresses it at once. Then tap Download.

Will my signature become blurry?

Small signatures stay clear at 20 KB. A very large photo may be resized a little. Cropping first keeps it sharper.

Is my file uploaded anywhere?

No. The image is compressed inside your browser and never leaves your device.
