If you need to batch convert your existing Jpg to WebP for WordPress, Optimus is the plugin. As the time of writing, it is estimated that only 68% of people can view and benefit from the WebP, Windows 10 and Edge does’t even support WebP, therefore it is not advisable to use WebP unless you are certain it won’t effect the end user.
