WebP is the Next-Gen image file format developed by Google and is also recommended by Google's own performance audit tool "Lighthouse". With WebP, it is possible to reduce image file sizes significantly, with same or almost same quality. Smaller image file sizes mean: Faster load times & better performance -> better rankings & user experience -> more sales! Not only, but especially mobile users using slow 2G/3G connections will be grateful and benefit highly from this improvement.
With our Extension WebP images can now be added to any Magento 2 store easily, with minimum effort & low cost.
