That's where Kraken.io fits in to the equation.

Kraken's optimization algorithms excel at determining the optimal balance of image quality and filesize, often greatly reducing image size while retaining sufficient quality for the vast majority of use cases. This means, for the publisher, more efficient use of storage and network bandwidth, and for the end user faster loading pages and apps, and a generally better user experience.
