Quick answer
To compress an image to 50 KB, upload your file above and FitToKB binary-searches the encoder quality to land at or just under 50 KB — never over. It runs entirely in your browser, free, with no signup and no upload.
50 KB is typically enough for a passport-style photo or a compact web image. FitToKB guarantees the result never exceeds 50 KB, so your upload form will accept it.
