https://www.w3.org/Bugs/Public/show_bug.cgi?id=20174 --- Comment #2 from Marcos Caceres <w3c@marcosc.com> --- from [1]: Some images are best suited to a specific file type for reasons such as file size optimization, alpha transparency, scalability, animation, etc. For example, a photo usually requires good color depth, but does not require alpha transparency or animation; JPEG or WebP are well-suited to these needs and offer good optimization between image quality and file size. Icons are often simpler in terms of color depth, but may require alpha transparency; the PNG format is better-suited to these needs. Sharing URLs for formats that are not interoperable across browsers is a problem in the wild. See issue 11. In a responsive design, images need to be displayed at different sizes. When possible, a vector format such as SVG might be most appropriate. There have also been proposals for new responsive image formats (see, for example, Christopher Schmitt's .net article). Although a web developer may want to use a specific image format, new or otherwise, the browser may not always support it. Currently, developers are forced to abandon the most suitable image format in favor of one that has good user agent support.
