什么是.gif文件？

GIF (Graphics Interchange Format) is a bitmap image format famous for its support of animations and transparency. Created by CompuServe in 1987, GIF uses lossless LZW compression but is limited to 256 colors per frame. This makes it ideal for simple animations, icons, and graphics with flat colors, but poor for photographs. GIF animations have become a cultural phenomenon on social media, messaging apps, and meme culture.
