What is a GIF file?
GIF stands for Graphics Interchange Format. It’s a bitmap image format developed by CompuServe in 1987. It became popular on the web due to its ability to support short animations and transparent backgrounds.
GIF uses lossless compression but is limited to 256 colors, making it less suitable for complex images or photographs. Still, it's widely used for memes, simple graphics, and looping animations.
How to open GIF files
GIF files can be opened by almost any device or web browser. They automatically play animations in apps and browsers without extra software.
You can also edit GIFs in specialized tools like GIMP or convert them using online services such as AnyConv.
