Compress Image to a Target KB
Get an image under an exact file-size limit for a form or upload. The tool bisects the JPEG/WebP quality to hit your target, and only downscales the pixels if compression alone can't get there. Everything happens in your browser.

FAQ
- Will the quality drop?
- Some, yes — that's how a smaller file is achieved. The tool keeps quality as high as it can while meeting your target; if the target is very small it will also reduce the dimensions.
- Is anything uploaded?
- No. The compression runs on your device.
