WordPress 5.8 is adding WebP support. 🖼️
As Adam Silverstein notes, as long as your server supports WebP, you should be able to upload
.webp files and use them like you would any other image. Developers can also fine-tune the compression quality setting.
The media component team exploring the option of having WordPress perform the image format conversion on uploaded images and adopt “WebP as the default output format for sub-sized images.”Adam notes:
“By switching to WebP as their default output format, users won’t need to do anything and will benefit from faster sites because images will be 25-40% smaller, with no loss of quality. Hosts will benefit from reduced memory usage for compression, and reduced storage and bandwidth requirements for images.”
