GIF Full Form is Graphic Interchange Format. It is often pronounced as ‘giff’ or ‘jiff’. It is a file format of bit map and is used by the World Wide Web. GIF was introduced in 1987 by CompuServe. Ever since, it has become widely popular because of its portability and support system. The GIF format supports around 8 bits for each pixel and for every image.
GIF supports various resolutions as well as colors. It is highly effective with scanned images like illustrations than color pictures. This is due to its limitations of 265 colors. However, it includes data compression. The advantage with GIF is, here, the images are effectively compressed to reduced file sizes with no degradation in the quality of the image. This is because, it applies LZW or Lempel-Ziv-Welch Lossless Data Compression.
