WebP is a new image format that provides lossy compression for photographic images. In a large scale study of 900,000 web images, WebP images were 39.8% smaller than jpeg images of similar quality.
A WebP file consists of VP8 image data, and a container based on RIFF. The standalone libwebp library serves as a reference implementation for the WebP specification and is available at this git repository and as a tarball. Webmasters and web developers can use the WebP image format to create smaller and better looking images that can help make the web faster.
