How to use the Compress Image to 100 KB
- Drop one or more photos onto the box — Target file size is already set to 100 KB.
- Pick an output format if you need one (JPEG works everywhere; WebP is smaller).
- Each image is saved at the best quality under 100 KB. Check the before/after view, then download one image or all as a ZIP.
Where 100 KB limits come up
100 KB is a common limit for profile photos, job applications, visa and government forms, and a good target for fast-loading website images.
How it fits the image under 100 KB
Instead of guessing a quality, the tool tries qualities and keeps the highest one that stays under 100 KB. If even low quality is too big, it reduces the width and height step by step — so text and faces stay as sharp as the limit allows. PNG images are reduced by lowering the number of colors first.
Tips
Most phone photos reach 100 KB at a quality that looks almost identical on screen once they are around 1600 px wide or smaller.
Need a different size? Change Target file size on the page, or use the image resizer for exact pixel dimensions.
