MKV files, also known as Matroska, appeared in 2002. The MKV file extension is used in the Matroska open standard Multimedia container. MKV is a video format that allows you to store multiple audio and video tracks, subtitles, etc. This media file format has become popular because it supports multiple compression algorithms, so MKV files are relatively small in file size while maintaining high-quality media content.
