Google Chrome Labs has just revealed Squoosh, an in-browser image compression tool that can use non-browser image codecs to compress images without much loss in quality. The app can also be run offline after it is loaded in a browser at least once. Squoosh is aimed at web designers that hope to reduce web page load times by using compressed images.

good app but there is no option to insert more then one image to convert, it allows to convert images one by one, that is time consumption, I must give this excelent app 2 stars if the option is available here.......
Best webp converter I could find. But it took me a whole, whole Google is filled with quite bad online converters...
