In our web design studio we use webp every day with jpg fall back for responsive web design. It would be really nice when webp is implemented in Studio 2 especially for jpg to webp converting and export. We use an other app for conversion now. Many developers using Topaz products will be delighted!
Webp is supported by Microsoft Edge, Firefox, Chrome browsers and many more. The only exception is Safari, but to see the webp images on my iMac I use the webp viewer at the moment (not very handy!).
