What is WebP?
WebP is an image format developed by Google. It has been developed to replace the conventional image formats (GIF, JPG, and PNG) and has a great advantage in that a WebP image has a very small file size.
Why should you use WebP?
Using the WebP format can reduce the file size of an image when compared with using the other conventional formats. Especially if the image is an animated image, or it shows actual objects and contains alpha channel, the file size can be much smaller by using the format.
