8 Best YouTube to MKV Converters

A YouTube to MKV converter is a software or online tool that allows you to download and convert videos from YouTube into the MKV file format. MKV is a popular multimedia container that stores high-quality video, audio, and subtitle tracks in a single file. It’s widely used for storing high-definition videos and due to its flexibility and support for various codecs. But which tools to use if you want to convert a YouTube video to MKV? We’re about to find out.

How to Choose the Best YouTube to MKV Converter

When picking a YouTube to MKV converter, make sure you check these facets:

  • Ability to download YouTube videos in multiple formats

Well, this is the primary and most important functionality. YouTube video downloaders and converters allow you to input the URL of a YouTube video and then fetch and download the video file from YouTube's servers.

  • Support of MKV

Check beforehand if the tool actually can convert the video to MKV, not just download the file in the same format it has been uploaded. MKV files can support various video and audio codecs, so you may have options to choose the quality and format of the output file.

  • Supported video platforms

Ensure that the converter supports the specific video platforms you want to download content from, such as YouTube, Vimeo, Facebook, or others. Some converters are limited to certain platforms.

  • Video quality

Look for a converter that allows you to select the video quality you prefer. Some converters offer options like 4K, 1080p, or 720p, depending on the source video's availability.

  • Batch downloading

If you often download multiple videos or playlists, consider a converter that supports batch downloading. This can save you time and effort.

  • Audio extraction

If you want to extract audio from videos, check if the converter supports this feature and offers various audio formats, such as MP3, M4A, or others.

  • Updates and support

Ensure that the converter receives regular updates to stay compatible with changes on video platforms. Reliable customer support is also valuable if you encounter issues.

  • Compatibility

While MKV is a versatile format, not all media players may support it out of the box, for instance, Mac computers. However, many popular media players and devices can play MKV files, and you can find codec packs or plugins to enable support on others.

A few more tips before we start:

  1. But be sure to use such converters responsibly and respect the rights of content creators.

  2. Always exercise caution when downloading software or using online tools, as some may contain malware or engage in questionable practices. It's essential to choose a reputable and trustworthy YouTube to MKV converter if you decide to use one.
