Why Convert MKV to AVI?
MKV (Matroska Video) is a modern, flexible container format that supports multiple audio, video, and subtitle tracks. However, it's not universally supported, especially on older devices and software. Converting to AVI ensures better compatibility with a wide range of systems, particularly older media players and devices.

Frequently Asked Questions
Will I lose quality when converting MKV to AVI?
There may be some quality loss during conversion since AVI doesn't support some of the advanced codecs that MKV does. Our converter uses settings that balance quality with compatibility to ensure the best possible output. For most viewers, the difference won't be noticeable during normal viewing, but videophiles might notice slight differences.
What happens to subtitles when converting from MKV to AVI?
MKV supports multiple subtitle tracks embedded within the file, while AVI has more limited subtitle support. By default, our converter doesn't include subtitles in the AVI output. If you need subtitles, you might want to consider extracting them separately from your MKV file or choosing a different output format like MP4 which has better subtitle support.
Is AVI still a relevant format in 2025?
While newer formats like MP4 and WebM have become more popular, AVI remains relevant for compatibility with legacy systems, older media players, and certain specialized software. Many DVD players, older TVs, and industrial/commercial video systems still use AVI as a standard format. Converting to AVI can be useful when you need maximum compatibility with these older systems.
