Now that the latest versions of Safari, Chrome, Edge, and Firefox all have compatibility with the .webp image format, it would be really good to have automatic image resizing for that format so that we can remove the "Serve images in next-gen formats" warning on PageSpeed Insights.
Thank you for the feedback everyone! Moving this to “in planning” as we are working on automatic image resizing for .webp images.
I wanted to provide a quick clarification. Currently we automatically serve images in WebP format for browsers that support it (with a few exceptions, such as GIFs). If you are still seeing the recommendation in Google PageSpeed Insights to "serve images in next-gen formats" it is because the conversion happens server side and the file extension in the URL does not change. However, you should still see an improvement in performance because of the image conversion. You can learn more about this feature in our developer documentation here.
