No, it isn’t currently possible to only use WebP images. As WebP isn’t fully supported on all browsers, best practice is to retain a fallback to the original PNG or JPG. Also, the fact that the images aren’t visible in the Media Library without the JPG or PNG present is not something that our plugin would affect. That’s a function of WordPress.
If you add that option (with some warning about this compatibility), it would be nice.
In my case I need to use only .webp because my visitors use only modern browsers (not internet Explorer) and I need only small files on hosting.
At this time if I use any converter to webp, I have on server both files. So if you add that feature in near future your plugin will be a first usefull for that case.
If I need only webp (without fallback images) only one choice is convert images before upload. And that is not comfortly :/
In modern browsers have .webp great support https://caniuse.com/?search=webp
Thank you for your time
I would recommend checking to see if someone has already suggested something like this or adding it as a suggestion to our feedback: https://feedback.ewww.io/
We use that to help determine our development focus.
