How to Convert ISO to MP4 Free on Win & Mac? Top 8 Ways in 2025

Why You Need to Convert ISO to MP4?

Here, let's first check the reason why ISO to digital conversion is necessary.

ISO image files are in a large size

ISO image^[WIKI] files are created by people as a digital backup of the DVD content on an external disk, hard drive, or others. So they contain the entire contents of a DVD which is why ISO files are normally a large size. Usually, a 90-minute ISO ranges from 5GB to 8GB. If you don't expect the ISO files to take too much space, converting ISO to MP4 is a good choice.

ISO image files can not be played on various devices

Apart from this, ISO files are not as compatible with the MP4^[WIKI] format. They cannot be directly played on various mobile and other devices, such as smartphones, Xbox One, PS4, TV, etc., while the MP4 format can. Thus, converting ISO files to MP4 can lead to easy playback, sharing, and editing on various devices without any hassle.

Apart from that, we will show you the 8 best ways to convert your large ISO files to high-quality MP4 file for compact storage and smooth playback.
