Compress Image to 100KB

Add your image — it's compressed to 100 KB automatically. The tool binary-searches the JPEG quality for the largest value that still fits under the target; if even the lowest sensible quality is too big, it scales the dimensions down step by step until it fits.

The tool always picks the HIGHEST quality that fits your target, so you never lose more than the size limit forces. Tight targets (like 20 KB) on large photos will visibly compress — that's the trade-off the form's limit imposes, not a flaw of the tool.

No — compression runs entirely in your browser. That matters here more than anywhere: these images are usually IDs, signatures and application photos.

JPG, PNG and WebP input. Output is JPG by default (accepted by virtually every form) or WebP if the site accepts it — WebP fits noticeably more quality into the same kilobytes.

Yes — free, unlimited, no signup and no watermark.
