Sumatra PDF adds support for WebP images. Till now you can able to view Webp images natively in Windows through Windows Photos Viewer, but for that you need to install codec provided by Google. FYI, you can still see WebP images in Chrome and Opera by dragging and dropping them, now an Windows app that supports WebP image format has joined the list and its not a browser, it’s a PDF reader- Sumatra PDF now displays WebP images also, drag and drop them onto program window.
