Automatic 100KB image optimization

The tool first adjusts image quality without changing dimensions. If that is not enough, it carefully reduces the dimensions until the file fits below 100KB. This gives you a useful result without guessing quality percentages yourself.

Compress image to 100KB FAQ

Will the result be exactly 100KB?

The output will be 100KB or smaller. Exact file size can vary slightly because every image contains different visual detail.

Does the tool change image dimensions?

It keeps the original dimensions when quality adjustment is enough. Dimensions are reduced only when necessary to meet the 100KB limit.

Which output format should I choose?

Choose JPG for broad compatibility. WEBP can produce a smaller file at similar visual quality for modern websites and apps.
