WebP Express is a free plugin that can create images that are less than half the size of a JPEG. It can convert JPEG and PNG files to WebP format, regardless of how the images were uploaded to the server. The plugin works with media libraries, galleries, and images referenced by CSS.

At RiseServ, we recommend that our clients use WebP formats for their images instead of other formats. This ensures that their websites load quickly and efficiently, which can improve user experience and search engine rankings.
