Many government portals, university applications, and online forms cap uploads at 100 KB. This tool finds the highest JPEG quality that still fits the limit using a binary search, then progressively scales the image only if it absolutely has to.
FAQ
Why is my output above 100 KB?
Some images can't reach 100 KB without becoming unusable. Try a smaller pixel size or use WebP for better compression.
Does this work for passport photos?
Yes. Switch the size mode to Preset and choose a passport size, then keep the 100 KB target.
