JPEG vs. PNG

JPEG is an acronym of the Joint Photographic Experts Group. It is a general purpose lossy image compression standard that supports a large number of image types and file formats. It is used as the default format of the Internet.

PNG is an acronym for Portable Network Graphics, a popular file format and graphics container. It was designed by W3C (World Wide Web Consortium) as a replacement for GIF and other file formats. PNG can be losslessly compressed, resulting in a file size smaller than GIF, and has a simpler, cleaner format. PNG is often used as a part of the CSS, SVG, or HTML standards, and is included in some media formats, including MNG.
