How to reduce an image to 100KB
Drop your image above.
The target size is set to 100KB (you can change it).
Click Compress: the best possible quality under 100KB is found automatically.
How it works
- Photos and images (JPG, PNG, WebP, AVIF, HEIC)
- JPGs go through MozJPEG, often 30–70% smaller with no visible difference. PNGs are optimized losslessly with OxiPNG or reduced to 256 colors. WebP and AVIF roughly halve the size again.
Everything happens in your browser: your files are never uploaded to a server.
