GIF (Graphics Interchange Format) is a useful 8-bit-per-pixel bitmap image format created by CompuServe in 1987. Since then it has become wide used for its wide support and portability. GIF supports online drawings, pictures with blocks of solid colors, and pictures with sharp boundaries between colors. GIF is unsuitable for photographs due to its 256 distinct colors from the over 16 million representable in 24-bit RGB limitation. However, there is a hack that can overcome this limitation under certain circumstances. On the process of compressing, there is no information lost in GIF files.   

EMF (Enhanced Metafile) is a metafile format designed by Microsoft, and a successor to the older WMF format. EMF is a newer 32-bit version with additional commands. It is easy to read on MS Windows computer while harder to read on other platforms. EMF files are usually stored between 5 to 10 KB in size, and EMF images do not support transparency. The EMZ format is a compressed version of the EMF format. EMF+ is an extension to EMF that allows GDI+ records to be stored. There are two variations on the EMF+ format: EMF+ Only and EMF+ Dual

TIF/TIFF (Tag Image File Format) is widely and common used lossless image format in all platforms, such as Mac, Windows, Unix. With the ability of storing arbitrary number of bits per pixel and having variety of compression algorithms, TIFF is favored by most people, especially by graphic designers. TIFF supports CMYK, RGB, Lab, indexed color and grayscale with alpha avenue and Bitmap images without alpha avenue. When approving or adding new tags, it can extend TIFF format by using tags. That is, the image information can be stored and arranged.

Other image format definition:

PNM means Portable Any Map file format which is a connection of the PBM, PGM, and PPM formats. It can produce multiple output formats including PBM, PGM, and PPM, and see the differences between the three. PNM, a simple format easily and quickly to read and write, is principally used with Netpbm.
