About this tool

A 20 KB limit is one of the smallest you will see, often used for a small ID photo box on a government or exam form. This page opens Resize image with the target already set to 20 KB. The tool lowers the quality, and the pixel size if needed, until your photo fits.

How to use it

  1. Choose your photo, or drop it onto the box.
  2. The maximum file size is already set to 20 KB.
  3. Select Resize and download your photo once it fits.

When this is useful

  • A small ID or thumbnail photo box on a government form.
  • Exam registration portals with a strict photo size cap.
  • Any form field that says "under 20 KB" or "20 KB max".

Tips for best results

  • Start from a clear, well-lit photo — heavy compression shows more on a blurry original.
  • If you also need an exact pixel size, such as 200 by 200, set the width and height before resizing.
  • JPG reaches small sizes far more reliably than PNG; the tool uses JPG by default for a size target.

Good to know

At 20 KB a photo will show visible compression, especially in busy backgrounds. If your form allows a little more, 50 KB keeps noticeably more detail.

Questions and answers

Will my photo look blurry at 20 KB?

Some quality loss is expected at this size, especially for a large or detailed photo. A simple, well-lit headshot holds up better than a busy background.

Can I also set an exact pixel size, like 200x200?

Yes. Switch to By pixels, set the width and height, and the tool resizes and compresses together to meet both the dimensions and the 20 KB limit.

What if 20 KB cannot be reached?

The tool shows the smallest size it could reach and tells you to try a larger limit or a smaller pixel size.
