Introduction

To address the question about the reasons for compressing or converting DVD ISO files and converting them to MKV format, let's first understand the nature of ISO files.

An ISO file, often referred to as an ISO image, is a single file that contains the complete contents of an entire optical disk, such as a CD, DVD, or Blu-ray disc. While ISO images are commonly used to back up movie discs, they are usually quite large and may not be compatible with multiple playback devices.
In contrast, the MKV format (also known as Matroska Video) is much more versatile and user-friendly. Many media players on almost all platforms support MKV files. The format can contain multiple video and audio tracks, as well as associated metadata and chapters, in a much smaller file size than ISO

Given these advantages, converting DVD ISO to MKV is ideal for those looking to improve the compatibility and efficiency of their media storage and playback experience.
