What is a GIF?

GIF stands for Graphics Interchange Format and it is a type of raster image file format that allows for animations. GIFs are made up of a series of images (or frames) that are displayed in rapid succession, creating the illusion of motion.

GIFs are often used to create short, looping videos — often memes — that are posted online. They are most commonly used as a way to create animated images from popular culture on social media platforms like Twitter and Instagram. Animated GIFs can be created from scratch or they can be made from existing video footage.

For the more technically minded: GIF files are compressed using the LZW algorithm (also used by TIFF files), which helps to keep file sizes small while preserving image quality. This algorithm produces lossless compression, meaning that no data is lost in the compression process. GIF files are made up of GIF87a and GIF89a formats, which allow for animations and transparency.
