Quick answer
To compress an image to 1 MB, upload your file above and FitToKB binary-searches the encoder quality to land at or just under 1 MB — never over. It runs entirely in your browser, free, with no signup and no upload.
1 MB is typically enough for a full-resolution photo with plenty of detail. FitToKB guarantees the result never exceeds 1 MB, so your upload form will accept it.
