GIF is a legacy format best known for short animations and simple graphics. It supports a maximum of 256 colors per frame, making it unsuitable for photographs but perfect for simple animations, reaction images, and low-color graphics. While newer formats like WebP and AVIF also support animation with much better compression, GIF remains ubiquitous for sharing short clips online.
Best for: Animated images, memes, simple graphics, email signatures, chat reactions.
