GIF
GIF (Graphics Interchange Format) is a bitmap image format developed by CompuServe in 1987 that supports up to 8 bits per pixel, allowing 256 distinct colors from a 24-bit RGB color space. It uses lossless compression via the Lempel–Ziv–Welch (LZW) algorithm, making it suitable for simple graphics, logos, and images with sharp edges and limited colors. GIF also supports animations by storing multiple frames in a single file, along with transparency and interlacing for progressive display.
Developers should learn and use GIF for creating lightweight animated content, such as loading indicators, simple memes, or short instructional sequences in web and mobile applications, where small file size and broad browser compatibility are priorities. It is particularly useful for scenarios requiring transparency without alpha channels, like overlaying logos or icons on varying backgrounds, though it is less suitable for photographic images due to its color limitations compared to formats like JPEG or PNG.
