ISO image is always used for duplicating the entire contents of a disc so it's not surprising that an ISO image file is very large. As storing ISO files requires a lot of space, which is inconvenient to upload and share a large ISO file or make DVDs, you might as well compress ISO files to smaller sizes. And here you will get a good ISO compressor:

Therefore, when you download a movie from the internet, it is likely to be an ISO file. Excessive size is a common problem of ISO Images. It can consume more network bandwidth and time if you want to share a large ISO image file with others, not to speak of the storage space consumption. So we always need to compress ISO image files.
