Portable Network Graphics (PNG
) is a static file format for the lossless, portable, well-compressed storage and exchange of raster images (bitmaps). It features rich color control, with indexed-color, grayscale, and truecolor support and alpha-channel transparency. PNG is designed for the Web, with streaming and progressive rendering capabilities. It is supported ubiquitously in Web browsers, graphical authoring tools, image toolkits, and other parts of the creative tool chain. PNG files have the file extension ".PNG" or ".png" and should be deployed using the Media Type "image/png". PNG images may be used with HTML, CSS, SVG, the Canvas API, and WebCGM.
