    About MKV

    MKV is a video file type made for high-quality movies and shows. Choose it when you want to keep the best picture and sound along with extras like subtitles and multiple languages in one file.

    • •Excellent picture and sound quality, good for long-term storage and backups.
    • •Can hold multiple audio tracks (different languages or commentaries) and built-in subtitles you can turn on or off.
    • •Supports chapters and extras, so one file can feel like a full movie disc.
    • •Plays well on many media players and smart TVs, but most web browsers and some phones won’t play it without special apps.
    • •Files can be larger than MP4; pick MKV when quality and features matter more than saving space.
    • •Great choice for home media servers or organizing a movie library while keeping everything together.
