Compress an image to 100 KB

Set a target size and get a JPG at or under it. Runs in your browser, so your photo never leaves your device.

How to compress an image to 100 KB

  1. Drop up to 5 JPG, PNG or WebP images onto the box, or click it to choose them.
  2. The target is set to 100 KB. Change the number if your limit is different.
  3. Wait a moment while each image is compressed to fit.
  4. Check the new size and dimensions, then click Download.

When you need 100 KB

Many online forms for job applications, exams, visas and government services reject photos above a set size, and 100 KB is a common limit. A phone photo is usually twenty times that or more.

How it reaches the target

The tool lowers the JPG quality step by step until the file fits. If the lowest acceptable quality is still too large, it makes the image smaller in pixels and tries again, then shows you the new dimensions. The result is always a JPG.

If you only want a smaller file and have no exact limit, the image compressor gives you a quality slider instead.

Questions

Will the image dimensions change?

Only when lowering the quality is not enough. The page shows the final width and height, and says when the image was resized to fit.

What format is the result?

JPG, which most forms accept. Transparent areas in a PNG or WebP become white.

What if my image is already under 100 KB?

If it is a JPG already under the target, the page tells you no change is needed.

Is my image uploaded anywhere?

No. The compression happens in your browser, so your photo stays on your device.
