The Graphics Interchange Format (GIF) is a bitmap image format that was introduced by CompuServe in 1987. It has since become widely used on the World Wide Web due to its portability and wide support. GIFs are particularly well-suited for images with limited colors, such as logos, simple graphics, and animations. GIF images use lossless data compression based on the Lempel-Ziv-Welch (LZW) algorithm, which reduces file size without sacrificing image quality. However, due to patent issues surrounding the LZW algorithm in the past, the PNG format was developed as an alternative. GIFs support transparency, allowing images to have transparent backgrounds. They are also known for their animation capabilities, where multiple frames are stored within a single GIF file, creating a short animated sequence. While GIFs are still used for simple animations and graphics, they are less suitable for photographs or images with complex color gradients due to the limited color palette (typically 256 colors).
