How to resize an image to 20 KB

  1. Upload your photo or scanned signature (JPG, PNG or WebP).
  2. The target is already set to 20 KB. If your form asks for a range such as 10–20 KB, keep 20 KB.
  3. If the form also lists pixel dimensions, enter them in the width and height boxes.
  4. Click “Resize to target” and download the JPG. Check the size shown under the preview before uploading it.

Why do forms limit file size in KB?

Government portals, exam boards, job sites and visa systems process thousands of uploads every day, so they cap each file at a fixed size such as 20 KB, 50 KB or 100 KB. A modern phone photo is often 2–5 MB — up to 250 times too big. Simply changing the width and height does not guarantee the file size, which is why uploads keep failing.

This tool measures the real file size after compression. It first lowers JPEG quality step by step and only reduces the pixel dimensions if the target still cannot be reached, so you keep the clearest possible image.

Other quick sizes: 50 KB · 100 KB · any size. Need a passport-style photo first? Try the passport photo maker or the DS-160 visa photo maker.

Frequently asked questions

How can I make my photo less than 20 KB?

Upload it here with the 20 KB target and press “Resize to target”. The tool reduces quality and, if needed, the dimensions until the file is just under 20 KB.

What size should a 20 KB passport-style photo be?

Forms commonly ask for around 200 × 230 pixels. Enter the dimensions from your form so the photo is the right shape as well as the right size.

Can I resize a signature to 20 KB?

Yes. Scan or photograph your signature on white paper, crop it closely and set dimensions such as 140 × 60 px if required. Signatures usually compress well below 20 KB.

Will a 20 KB photo look blurry?

At 20 KB a small photo can still look clear. Start from a sharp, well-lit original and avoid very large dimensions.

Is it free and safe?

Yes. It is free and your image is processed only in your browser.
