This article will introduce you to the top 6 free ISO converters. For your ease, we’ve divided the article into two parts, part one will help you to convert ISO files to MP4, AVI and other formats to make them device compatible, and part two will teach you how to convert disk/folder/files to ISO.

Main Types of ISO Converters and How They Work

Before choosing an ISO converter, it's useful to understand the two primary ways these tools are used. ISO converters typically help you either extract files from an ISO or create new ISO images from discs or data. Here's what you need to know:

1. Converting ISO Images to Digital Formats

This type of ISO converter transforms ISO files—which are usually complete disc images—into popular digital formats such as MP4, MKV, AVI (for video), MP3 (for audio), or simply extracts files and folders for everyday use.

🎯Typical Scenarios:

• Turning a DVD movie ISO into an MP4 file for playback on various devices.
• Extracting music, photos, or documents from an ISO image for direct use.

2. Creating ISO Images from Discs, Files, or Folders

These tools allow you to take a physical DVD, a folder like VIDEO_TS/AUDIO_TS, or any collection of files, and package them into a single ISO image. The ISO can be burned to disc, mounted virtually, or stored as a backup.

🎯Typical Scenarios:

• Archiving a DVD as an ISO image for easy storage or virtual playback.
• Combining files or entire folders into an ISO for convenient sharing or backup.

The two primary uses of ISO converters are extracting digital files from an ISO image and creating an ISO image from discs or files. For most everyday needs, these two categories cover nearly all common ISO conversion tasks.
