What is Compress an image to 100KB?
TL;DR: Type 100 KB as your target and Shrink44 binary-searches the quality and resolution to land at or just under 100KB — without uploading your photo.
Many government portals, exam boards and job applications require a photo under 100KB. Most compressors only give you a quality slider and leave you guessing. Shrink44 lets you set 100KB as an exact target and does the math for you.
It works by iteratively binary-searching the JPEG quality (and, if needed, the resolution) until the output lands at or just below 100KB — usually in 5–8 passes, all inside your browser.
