Due to better capabilities, support and convenience to carry, Graphics Interchange Format (GIF) has become very famous all over the world especially in web designing simple animations and icons. It was announced in the public in 1987 by CompuServe and is an image format of bitmap.It has great clarity and has a collection of 256 different colours and is capable of providing an image with 8 bits for a pixel. It also encourages the use of animations. Due to restriction in the use of colours, coloured photographs and other images with certain different colours are unable to be produced with GIF.
Compression can be done of the images of GIF format with the help of Lempel-Ziv-Welch (LZW). It is a technique that doesn’t affect the quality of the image but still reduces the size and is called as lossless data compression method which is perfect solution in web design when the files sizes matter.
