Hi,
Some browsers, Website builder supports the WebP format. WordPress doesn’t currently support WebP images by default. However, you can still use the WebP format on your site – it will require one or more additional tools / add-on.
You can try the following plugin,
Try “WebP Express” -> The plugin converts your images to WebP if the visitor’s browser supports them. If the browser doesn’t support WebP, a normal version of the image will be served.
Thanks!
We originally had WebP loaded
This plugin is worth it, but the images are still not shown.
If the plugin is not working as expected, I recommend you seek help through their dedicated support forum:

You can cause the media library to accept webp images by modifying the allowed MIME types through the ‘post_mime_types’ filter, but not all browsers will display such images. To allow non-supporting browsers to display images, you need a fallback jpeg image for them to use, then specify alternate sources in a <picture> element instead of a simple <img> tag.
