Are you looking for the best online tools to convert MKV to MP4? You are at the right place.

You’ve probably encountered the MKV video format and wondered how it differs from the more widely used MP4 format.

Some devices are easily compatible with any MP4 file type but cannot manage the MKV format. To overcome that barrier, we must convert the MKV files to a more acceptable format, such as MP4. But this task necessitates using the appropriate tool. This article will list some of the best MKV to MP4 conversion tools.

First, let’s dive in and learn about the MKV file and its use.

What is an MKV file?

<img alt="What-is-an-MKV-file" data- data-src="https://kirelos.com/wp-content/uploads/2022/10/echo/What-is-an-MKV-file.png" data- height="400" src="data:image/svg xml,” width=”800″>

MKV file, sometimes called Matroska Video, is a multimedia file format. Contrary to popular file formats, an MKV file can combine audio, video, and subtitles into a single file—even if those components employ various encoding techniques.

An MKV file player will open all of its components when you double-click on a single MKV file. You’ll also admire the MKV file format’s ability to be future-proof. The Matroska developers added many features to guarantee that the files would never go out of date. These are a few of these essential traits:

  • Rapid seeking
  • Assistance with chapters, menus, and metadata
  • Compatibility with online streaming
  • Diverse streams of audio and video 
  • Error recovery enables the playback of damaged data.
  • Hard-coded and soft-coded subtitle support

The MKV file, which supports practically every audio and video file, further enhances the format’s flexibility and user-friendly. Because it allows descriptions, ratings, cover art, and even chapter points, this file format is best for high-definition online videos.

Why is the MKV file used?

The MKV file format is used in the first place due to its open-source nature, which makes the code available to everyone, including developers worldwide, for free. 

Other container formats are mostly made up of proprietary code that has only been created by the original manufacturer and its authorized partners. The potential for more innovative solutions and widespread use is undoubtedly higher with open-source programs.

In the MKV format, soft subtitles are also available. A soft subtitle is a different subtitle track within the container that the user can toggle on or off. This function will be handy if you’ve ever downloaded an AVI video with unnecessary subtitles and couldn’t turn them off.

Chapters, DVD-like menus, multiple audio streams for adding audio tracks in various languages, and menus are all supported by the MKV format. 

Why does one need to convert an MKV file?

You may need to convert the MKV file to MP4 online for diverse reasons. Some of the most typical scenarios and circumstances are listed below.

1. MKV format is not supported

The MKV format’s incompatibility with a device or player is one of the most typical causes for conversion. You need to convert MKV files to a more widely used format like MP4 if your MKV video does not play on your mobile device, media player, or other devices because of the audio codec or other problems.

2. You have to free up some space on your computer or mobile device

Because MKV files are high definition, they consume a lot of storage space on your PC or media player. Therefore, converting MKV files to a lower-size format like MP4 makes sense if you run out of storage space.

3. Upload and stream videos

MKV videos are challenging to share, transfer, and broadcast over the Internet due to their weight and size. Therefore, converting MKV files to MP4 makes the procedure more accessible and seamless if you want to publish your videos on social media or other video-sharing platforms.
