ISO is a sector-by-sector copy of the data on an optical disc. An ISO image contains all contents of the disc, such as the menu, the main movie, every single track and information about the disc structure. Such kind of file makes up for the flaw in DVD that is vulnerable to scratch and can be easily transferred over the internet.

The regrettable things are that ISO images are stored in an uncompressed format (usually 4-8GB) and so far there is no mobile device supports ISO image. So if you want to play ISO image on iPhone, iPad, Android, or other devices, you need to convert ISO to MP4.

In this article, we'll explore a variety of ways to convert ISO to MP4, including both free and paid options.

Method 3. Convert ISO to MP4 for Free with VLC

Compatible OS: Mac, Windows, Linux
Free or paid: free

It's true that VLC can support you to freely rip an MP4 file from ISO image. And you can't blame it if it doesn't live up to your anticipation, for it's just freeware and the developer team members are not so enough as the paid products to constantly update the program to satisfy your every need. So in short, VLC is great in case you just need it to handle the unprotected ISO image conversion without any dent in your wallet.

Personally, I adore VLC media player a lot as it covers multiple features into one: video playback, video conversion, video editing and ISO image conversion. Yet, advanced GPU hardware acceleration tech is absent from this excellent toolbox. It only supports the basic "Video Decode Acceleration Framework", which actually has few influence on ISO image transcoding speed. I use VLC to convert THOR.iso (7.5GB) file and choose MP4 (H264) as output format. Have to admit that it's quite easy to conduct the conversion.


  • Free and open-source.
  • It's a multifunctional tool.


  • It does not have dedicated customer support.
  • It may not work with your encrypted ISO files.
  • Slow conversion.

Step 1. Open VLC Media Player on your computer if you already have it installed.

Step 2. Tap "Media" from the top menu and select "Convert/Save...".

Step 3. Click "+ Add" to import the ISO file you want to convert. Then, tap "Convert/save..." at the bottom.

Yes, you can use FFmpeg to convert an ISO file to an MP4 file. To do this, you need to open a command prompt or terminal window and enter the appropriate command. The command may vary slightly depending on your operating system and the specific ISO file you want to convert.

ffmpeg -i input.iso -c:v libx264 -crf 20 -preset medium -c:a aac -b:a 192k output.mp4

In this command:

  • input.iso is the name and location of your input ISO file.
  • -c:v libx264 specifies the video codec to use (H.264).
  • -crf 20 sets the video quality. Lower values produce higher quality but larger files, and higher values produce lower quality but smaller files. A value of 20 is a good balance between quality and file size.
  • -preset medium specifies the encoding speed and quality. The "medium" preset provides a good balance between speed and quality.
  • -c:a aac -b:a 192k specifies the audio codec to use (AAC) and the audio bitrate (192 kbps).
