Quick answer

To compress an image to 30 KB, upload your file above and FitToKB binary-searches the encoder quality to land at or just under 30 KB — never over. It runs entirely in your browser, free, with no signup and no upload.

30 KB is typically enough for a passport-style photo or a compact web image. FitToKB guarantees the result never exceeds 30 KB, so your upload form will accept it.

Frequently asked questions

How do I compress an image to 30 KB?
Upload your file to the tool above, keep the target at 30 KB, and download. FitToKB automatically finds the highest quality that stays at or below 30 KB.
Will the file go over 30 KB?
No. The engine only returns a result at or below 30 KB. If 30 KB is very small for the image, it lowers quality and, where allowed, resolution, and tells you if the target can’t be reached.
Does compressing to 30 KB reduce quality?
Some quality is traded for size, but FitToKB always uses the highest quality that fits 30 KB, so the loss is the minimum required to meet your target.
Is my image uploaded to a server?
No. Everything runs in your browser. Your file never leaves your device and nothing is stored.
