Optimizilla uses a smart combination of the best optimization and lossy compression algorithms to shrink JPEG and PNG images to the minimum possible size while keeping the required level of quality.

In the majority of cases this optimizer provides the best achievable image compression ratio, outperforming all other services and software.

Optimizilla is intended for using by web developers and publishers when a resource load time is of the essence.
