This plugin allows Paint.NET to load and save Google's WebP format. This plugin is bundled with Paint.NET 4.2.5 and later. If you need the features from a newer version you can still install the plugin. The plugin will override the bundled version if it has higher version number.   This plugin will only load the first frame of an animated image, to load all of the frames you will need to change the file extension to .awebp and use @midora's 'WEBP Animations and Images' File
