    The WebP plugin processes images in webP format on the frontend of your website. PNGs and JPEGS are converted to webP when the querystring parameter format=webp is added to the image URL.

    In the backend CMS you should see the original image rendered. You should not be seeing the webP conversion.

    You should inspect the image URL that the backoffice image is using with your browser web development tools to use to see why it is not being rendered.

    i had same issue, problem is that plugin ImageProcessor.Plugins.WebP requires additional DLL installed on hosting server

    Requires msvcr120.dll from the Visual C++ Redistributable Package for Visual Studio 2013 to be installed on the server.

    it's working only when there is no need to resize/optimise becouse then plugin is not used.

    you can install library from official microsoft downlaod page or use choco repository ->
