This plugin adds WebP support for media uploads within the WordPress application. WebP images will be generated only for new uploads, pre-existing imagery will not be converted to WebP format. By default, WebP images will only be generated for JPEG uploads, only the original uploaded file will still exist as a JPEG image. All generated image sizes will exist as WebP only. If you wish to change this behaviour, there is a checkbox in Settings > Media that – when checked – will alter the behaviour of this plugin to generate both JPEG and WebP images for every sub-size (noting again that this will only affect newly uploaded images, i.e. after making said change).
