Quick answer

To compress a JPG to 10 KB, upload your file above and FitToKB binary-searches the encoder quality to land at or just under 10 KB — never over. It runs entirely in your browser, free, with no signup and no upload.

10 KB is typically enough for a small profile photo, exam thumbnail or signature scan. FitToKB guarantees the result never exceeds 10 KB, so your upload form will accept it.

Frequently asked questions

How do I compress a JPG to 10 KB?
Upload your file to the tool above, keep the target at 10 KB, and download. FitToKB automatically finds the highest quality that stays at or below 10 KB.
Will the file go over 10 KB?
No. The engine only returns a result at or below 10 KB. If 10 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 10 KB reduce quality?
Some quality is traded for size, but FitToKB always uses the highest quality that fits 10 KB, so the loss is the minimum required to meet your target.
Is my JPG image uploaded to a server?
No. Everything runs in your browser. Your file never leaves your device and nothing is stored.
