I'll have to try that. There are lots of pictures I'd love to snag from my news site and they come up as WEBP.If you try to download images directly from an image search result (like on Google or Bing) usually it downloads as a WEBP and you have to upload it again to some site to convert it into PNG.
But if you're on Edge, and you're on edge, you can simply right-click the image, choose 'Edit Image', then save it and the image is downloaded as a PNG.
