How to Convert ISO to MKV With Original Data and High Quality

Part 1. Why Convert ISO to MKV

An ISO file is a type of optical disc image file that contains all the contents and structure of the disc, like a complete copy of the disc. For converting ISO to MKV, there are the following reasons:

Compatibility: ISO files have limited compatibility on different operating systems and devices. MKV is an open multimedia container format that can accommodate a variety of audio, video, and subtitle tracks, and has wide support on different platforms. Multiple audio track and subtitle supports are why saving ISO as MKV to keep all the original data. If your source is a DVD, you’ll need to rip DVD to ISO format before converting it to MKV.

File size: ISO files are usually large and take up more storage space. The MKV format supports efficient video encoding and compression algorithms, which can reduce the file size to a more reasonable range, thereby saving storage space.

High-quality video: The MKV format supports advanced video coding standards, such as H.265, H.264, etc., which can provide high-quality video output. What's more, MKV also supports lossless audio encoding like FLAC, so that audio quality is good.
