ShrinkToKB, the strict-limit image compressor

Field notes

The tool accepts dropped, pasted, or selected images and lets users choose both a byte limit and output format. Its documented strategy is to search encoding quality before changing dimensions, which preserves size where possible while meeting strict upload rules. The page lists five preset limits from 20 KB to 500 KB, supports five input formats, and says browser-side processing keeps the image, filename, dimensions, and result from reaching the service.
