Reduce the Weight and Not the Quality

You need to be confident that the quality of the results you are getting have not been compromised for the sake of getting the smallest possible file size. While it is possible to reduce any image to a tiny fraction of its original size, that approach often leads to a serious amount of visual degradation. Kraken.io's optimization pipeline offers tremendous savings, with results that stand up to close inspection, each and every time.

User experience is all about speed. A faster site will make your users happier. Happier users will buy more of your product and refer you more business. A faster site will get you more traffic and gain you more leads - all of which will contribute to the success of your business. If your site is image-rich, you will need to be extra vigilant in order to keep request sizes down. Kraken.io will help you with that.

Optimize for Mobile and Tablets
