Have you ever downloaded a video file only to find out that it won’t play on your phone or computer? It often happens because of the file format. MKV is a popular video container… Think of it as a box that can hold video, audio, subtitles and more but not all your devices or apps can open it. Also, you know it is common knowledge that the MP4 format is the most universally compatible format for videos and audios. In this post, we’ll go ahead and explain why you might need to convert MKV to MP4. You will also be exploring the differences between these two formats and we’ll be walking through some of those easy ways to do the conversion without losing quality.<\/p>

<\/a>What’s the Difference Between MKV and MP4?<\/strong><\/h2>

Both of these formats MKV and MP4 are container<\/em> formats which basically means that they can contain multiple tracks i.e. video, audio, subtitles, etc. within them. But they have their own different strengths and weaknesses as well. MP4 (MPEG-4 Part 14) is a very common container format for video and audio. It’s in fact the most commonly used video format these days and can store video, audio, subtitles, text, and still images as well.<\/p>

MP4<\/a> is mostly known for its wide compatibility as it works on Windows, macOS, iOS, Android, smart TVs, and you name it… pretty much any device. MP4 files are using compression to keep file sizes small, which means you only get a slight<\/em> loss in the actual quality.<\/p>

MKV (Matroska) on the other side of things is an open-source container format that, with time, has become popular for keeping that high-quality content. Matroska format is designed to hold multiple<\/em> video\/audio\/subtitle tracks inside it in one file. An MKV file can contain different language audio tracks and subtitles all together housed in it.<\/p>

Importantly, MKV supports lossless codecs… so it can deliver truly high-quality video. But such a richness comes with bit of trade-offs as well. MKV files are much larger than those other formats and all of those devices or players or yours cannot open MKV by default.<\/p>

If we have to say this whole thing in one line, it can be stated that this MP4 is the universal workhorse that has great compatibility and that too with a small size but on the other side MKV is a flexible but a high-fidelity container, which has multiple streams and are often bigger files by nature.
