How to compress an image to 100 KB

  1. Drop your photo on the box. The target is already set to 100 KB.
  2. The tool lowers the quality step by step, and the size only if needed, until the file is under 100 KB.
  3. Check the result with Compare and download it.

Need another limit? Click 20, 50, 200 or 500 KB, or type your own size.

Why 100 KB?

Many job portals, university and government application forms accept photos and signatures only up to 50, 100 or 200 KB. A phone photo is usually 2–5 MB, so it has to be reduced 20 to 50 times. Choose JPG output for the widest acceptance.

Tips

  • For passport-style photos, crop the image to your face and shoulders first: less area means more detail at the same size.
  • If the form also asks for dimensions in pixels, set Resize to the closest value.
  • Scans of documents stay readable at 100 KB when they are black and white or grayscale.
