GIF File: 

The GIF file is used on the internet, this is because of the size of the file; this is because of the low file size. This is so that the public can download the file easily even if their internet is slow. The GIF file can create an animation due to its multiple layers; GIF files are mainly popular on the website Tumblr. My-second-GIF-

JPEG is made up of a single layer, this file is used on the Internet, when an edited image is saved as a JPEG all of the layers that were created during editing will be merged together creating one layer, once this has been saves there can be no editing done to any of the layers that are now merged together.
