WebP is an open-source file type that uses predictive compression to create images that are ideal for web pages and mobile applications. WebP images are as much as 30 percent smaller than JPEG (JPG) and Portable Network Graphics (PNG) files, with similar visual quality. WebP images load quickly on web pages and mobile applications.
