A GIF (which stands for Graphics Interchange Format) is a type of digital image file that can show a short, repeating animation. Unlike a regular photograph that just sits still on your screen, a GIF plays the same few seconds of movement over and over in a continuous loop.

You've probably seen GIFs all over the internet: a cartoon character waving, a cat doing something silly, or a scene from a movie playing repeatedly. They're popular because they capture a moment or reaction in a way that feels more alive than a still picture but simpler than a full video. Someone might send you a GIF of someone laughing to show they think something is funny, or a GIF of a person shrugging to express confusion.

What makes GIFs special is that they load quickly and work on almost any device or website, which makes them perfect for sharing quick reactions, jokes, or memorable moments online.
