What is a GIF?

A Gif, pronounced "Jif," is a simple image format (as opposed to .img, .jpg, and .png) that only consists of 256 different colors. In the RGB (red-green-blue) color system there are 256^3 or 16,777,216 different colors.

So when comparing the the number of colors supported by gif files to image files that follow the RGB system, RGB color system has 65,536 x the amount of colors that gif images have. Gif images are dominant amoung simple web page images because they take up less space (less bytes of information to process and render). The smaller the file, the faster it will load, and for websites this is extremely important because people can lose interest in a website in the millisecond range.
If pictures are not present from the start people will think BORING. All gif files end with the extensions .gif so to search google strictly for gif images type file: .gif  into the search bar

Gif files are used for simple animations as well! Here are some cool examples:
