What is a MKV File?

MKV (Matroska Video) is a flexible, open-source container format that can hold unlimited video, audio, subtitle, and picture tracks in a single file. It's popular for storing movies and TV shows due to its ability to contain multiple audio tracks and subtitles. While MKV offers great flexibility, it's not universally supported by all devices and media players. Converting to MP4 ensures your videos will play on any device, from smartphones to smart TVs.
