WebP is a raster graphics file format developed by Google intended as a replacement for JPEG, PNG, and GIF file formats. It supports both lossy and lossless compression, [8] as well as animation and alpha transparency. Google announced the WebP format in September 2010, and released the first stable version of its supporting library in April ...
The WebP container (i.e., RIFF container for WebP) allows feature support over and above the basic use case of WebP (i.e., a file containing a single image encoded as a VP8 key frame). The WebP container provides additional support for: Lossless compression – An image can be losslessly compressed, using the WebP Lossless Format.

PNG – inside an "iTXt" text block with the keyword "XML:com.adobe.xmp" GIF – as an Application Extension with identifier "XMP Data" and authentication code "XMP" MP3 – inside the ID3 block as a "PRIV" frame with an owner identifier of "XMP".
Such RAW codecs are currently available from Canon, Nikon, Olympus, Pentax, Sony and for Adobe DNG. Many applications on Mac OS X use either the Core Image or QuickTime APIs for image support. This enables reading and writing to a variety of formats, including JPEG , JPEG 2000 , Apple Icon Image format , TIFF , PNG , PDF , BMP and more.

Most computer images are stored in raster graphics formats or compressed variations, including GIF, JPEG, and PNG, which are popular on the World Wide Web. [4] [5] A raster data structure is based on a (usually rectangular, square-based) tessellation of the 2D plane into cells, each containing a single value. To store the data in a file, the ...
