The image is set out is bitmap image and it consists of a file extension .gif. In 1987, It was launched by CompuServe. The chief idea behind its development is to create an image format that is independent of the platform. Lempel-Ziv-Welch (LZW) lossless data compression method is used to compress GIF images. This method is used to diminish the size of the file without lowering the standard of the image.

The 8-bit format is used in GIF images which keep up with 256 colors. To make new colors, these 256 colors cannot be mixed. It is in-demand on the internet because of its small size and transportability and manageability specifications. It is contemplated prime for line art with a limited amount of colors, images with huge flat regions of color and images that require being high- spirited or animated.
