Can you Upload MKV to YouTube?

Undergoing experiments, although MKV is not the list of YouTube supported formats, we got the positive conclusion that YouTube actually supports MKV files, so you can upload MKV to YouTube directly. However, due to the HD quality of he MKV video, MKV videos are much larger in size than other formats at the same length. Thus, it takes more time to upload an MKV video to YouTube.

So if you want to upload a long MKV video or an MKV movie to YouTube, you’d better convert MKV to a YouTube supported format that is smaller, so that you can make a quick transmission to save your time. Also, you can choose either one based on your needs. Below are the supported video formats by YouTube.

  • MP4
  • AVI
  • MPG or MPEG
  • WMV
  • 3GPP
  • FLV
  • MOV
  • M4V
  • WEBM

For converting MKV movie to YouTube, a professional MKV to YouTube converter is highly recommended, because it not only concludes all video formats you need but also can make bulk conversions in a super fast speed without data loss.


Final Words

After reading this article, I believe that you must have grabbed the most appropriate method for yourself to download YouTube to MKV on your device for enjoyment. However, considering to the copyright and privacy of the uploaders, please don’t disseminate or monetize the downloaded videos without permission.
