At 100 KB most photos survive compression with barely visible quality loss — if the compressor is smart about it. ExactKB binary-searches the quality setting to use every kilobyte you're allowed, instead of overshooting to a needlessly small, needlessly ugly file.
How it works
- Check the target. This page is preset for the spec above — adjust any number to match your exact form.
- Drop your photo. ExactKB finds the best quality and dimensions that land inside the size window — including padding files up when a form has a minimum size.
- Download. The file fits the requirement on the first try.
FAQ
Will it look worse than the original?
At 100 KB, usually imperceptibly — ExactKB uses the highest quality that still fits your limit.
Is my photo uploaded to a server?
No. ExactKB runs entirely in your browser. Your file never leaves your device — this page even works offline.
