JPEG - jpg - Joint Photographic Experts Group
This is a common image compression type. Best used for photographs as they favor smooth gradients and softer images. The name comes from the committee that created the standard in 1992.
GIF - gif - Graphics Interchange Format
Gif was introduced by CompuServe in 1987. GIFs are suitable for sharp-edged line art (such as logos) with a limited number of colors. This takes advantage of the format’s lossless compression, which favors flat areas of uniform color with well defined edges.
PNG - png - Portable Network Graphics
PNG was created to improve upon and replace GIF. It is able to handle grades of transparency.
