The MKV file format has been increasing in popularity ever since high-resolution monitors became widely available, and so there has been a corresponding increase in demand for formats that can retain HD video quality. You can preserve HD quality in your videos by converting them to MKV, which also enables you to choose from multiple audio and subtitle tracks. And that is how the MKV format got its name – it's officially called Matroska Video after the Russian matryoshka dolls because all the video, audio, and subtitle tracks are kept within a single file, much like the nesting dolls are stored within one another.
If you want to convert video from your DVDs, Blu-rays, or elsewhere to MKV, or burn MKV to DVD, your best bet is a simple yet powerful MKV converter like Movavi Video Converter. It’s an all-in-one tool for Windows or Mac that converts video and audio between more than 180 media formats (AVI, MP4, MOV, MPG, FLV, M2TS, TS, WMV, H.264, DivX, AVCHD; MP3, WAV, FLAC, VOB, and more) and saves them to play on more than 200 mobile devices, including Apple iPad, iPhone, and iPod, Sony PS4 and PS3, Xbox One, and many smartphones, tablets, and media players. Use this handy application to trim, resize, and enhance the quality of your clips and movies too.
In this article, we’ll show you two ways to convert files to MKV – using a desktop app or an online converter. You can also check the comparison table to learn more about the differences between MKV and MP4 formats.
