gif The .gif filename extension refers to the GIF graphical file format created by CompuServe in 1987. The format is from the class of raster graphics which uses a dot matrix type data structure of orthogonally placed pixels, each with their own color information. The file format has a rich history of usage in storing sprite data for video games especially those released in the early 90's. The GIF format has also been used in low-resolution animation clips distributed over the internet, and in design of sharp-edged art that utilize a palette of a few colors up to a max of 256 colors. The GIF file format has its advantage in its compression technique, which limits file size but does not compromise image quality. The file format natively opens on many of the popular web browsers.
bmp The bitmap image file format or bmp file for short, is a raster graphics image file. It uses a dot matrix data structure to represent pixelated points of color and to store digital image information. The format optionally supports compression and has wide cross platform support on all the major computer operating systems. Because bmp files are raster graphics files, image resolution is constrained meaning images in this format will not scale without loss in quality. This is in contrast to vector graphics images that can scale to arbitrary resolutions.
