JPEG (pronounced "jay-peg") is a standardized image compression mechanism. JPEG stands for Joint Photographic Experts Group, the original name of the committee that wrote the standard. 

JPEG is designed for compressing either full-color or gray-scale images of natural, real-world scenes. It works well on photographs, naturalistic artwork, and similar material; not so well on lettering, simple cartoons, or line drawings.

Tagged Image File Format (abbreviated TIFF) is a file format for mainly storing images, including photographs and line art. Originally created by the company Aldus for use with PostScript printing, TIFF is a popular format for high color depth images, along with JPEG and PNG. TIFF format is widely supported by image-manipulation applications such as Photoshop by Adobe, GIMP, and Paint Shop Pro by Jasc, by desktop publishing and page layout applications, such as QuarkXPress and Adobe InDesign, and by scanning, faxing, word processing, optical character recognition, and other applications. Adobe Systems, which acquired the PageMaker publishing program from Aldus, now controls the TIFF specification.
