For those who’ve been asking, the wait is over: we’ve just added support for WebP images in Webflow!
For the uninitiated, WebP is a modern, more compact image format that lets you serve high-quality images at a smaller file size than traditional JPEG and PNG formats — which means your site loads faster (and ranks better) without compromising the quality of your images.
A note on browser support: while a very small percentage of old browsers don’t support WebP images, WebP is considered very widely supported (with coverage by more than 96% of browsers). That said, if your site visitors tend to come from browsers (such as IE 11), you may want to stick with more traditional image formats.
