A GIF, or Graphics Interchange Format, is a popular image file format widely used on the internet. Unlike static images, GIFs support animation and can display a series of frames in a loop. Developed in 1987 by CompuServe, GIFs use lossless compression, preserving image quality while keeping file sizes relatively small. The format gained immense popularity for its ability to convey short, looping animations, making it a staple in online communication. GIFs are commonly employed in memes, reactions, and social media posts, serving as a dynamic and entertaining means of expressing emotions or conveying messages in a concise and visually engaging manner.
