To use WebP, you’ll first need to convert your existing images to the format. Google has proposed using WebP for animated images as an alternative to the popular GIF format, citing the advantages of 24-bit color with transparency, combining frames with lossy and lossless compression in the same animation, and as well as support for seeking to specific frames.In this excerpt from his eBook “ The WebP Manual,” developer and author Jeremy Wagner will show you the many ways you can convert your existing images to the WebP format. The frame speed data and extra animation frames are stored in extra chunks (as provided for by the original PNG specification). The first frame of an APNG file is stored as a normal PNG stream, so most standard PNG decoders are able to display the first frame of an APNG file. WebP-related software is released under a BSD license. As a derivative of the VP8 video format, it is a sister project to the WebM multimedia container format. WebP is an image format employing both lossy and lossless compression. It also retains backward compatibility with non-animated PNG files. It allows for animated PNG files that work similarly to animated GIF files, while supporting 24-bit images and 8-bit transparency not available for GIFs.
