How to compress a JPG
Drop your JPG photos above.
Pick Light, Recommended or Strong, or a maximum size in KB.
Click Compress and download your smaller JPGs.
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.
