GIF89a

GIF89a is a version of the Graphics Interchange Format introduced in 1989, designed for digital images. It supports simple animations by storing multiple images within a single file that can be displayed sequentially, creating motion. It uses a limited color palette (up to 256 colors) to keep file sizes small, making it suitable for web graphics and short animations. The format also includes transparency features, allowing parts of the image to be see-through. Overall, GIF89a is a popular format because it balances image quality with small file size and supports basic animated content.
