  • Once you've downloaded the VLC media player, you can manually convert an MKV file to MP4 on your Mac with its built-in conversion feature.
  • An advanced way to convert MKV to MP4 is through Appgeeker Video Converter, which offers lossless quality for Mac or PC users.
  • You can also use Handbrake—an open-source transcoder that can help you convert high-definition MKV files to MP4 on a Mac.

Here you'll learn how to convert .mkv file to MP4 in several easy ways.

Mac users may have a tough time playing .mkv movies or TV shows, because so few formats are supported by Apple programs like QuickTime, yet MKV is not included. Apart from playing in a third-party program like VLC, you could convert MKV to MP4 on Mac—if you have the right converter that won't lose your movie's quality. Unlike MKV, MP4 (MPEG-4/H.264) is compatible with virtually all portable devices and programs including Quicktime and iMovie.

Known as the versatile Matroska Multimedia Container, the MKV is an open-source container storing HD video, audio as well as subtitle tracks, working in a larger size than MP4. If you want to get the same HD video in MP4 format, follow this guide to find the best MKV to MP4 converters available.

Option 1. VLC Media Player

VLC Media Player is a great cross-platform multimedia player for both Mac and PC users who want to play most video formats including MKV and MP4. Further, the program can also function as a video converter, and make it easy to convert your MKV files to MP4 on a Mac as you like.

To convert your MKV files to MP4 using VLC Media Player, you can follow the instructions:

  • Install VLC Media Player on your computer and then launch it.
  • Select File > Convert/Stream at the top left corner of your screen.
  • You can also press Command + S to open the Convert/Steam window.

  • Click on Open Media to import an MKV file from your Mac.
  • If your .mkv file is on your desktop, you can drag and drop it here.

  • At the Profile section, select Video -H.264 + MP3 (MP4) as your desired output format.
  • Next, click Save as File > Browse to choose your desired destination path.
  • Once that's set, click on Save again to commence the conversion.

You can customize your output settings by adjusting the encapsulation, video codec, and audio codec features. The encapsulation feature controls how the data in your file is arranged while the video and audio codecs determine the file quality. But when you prepare to choose a proper resolution like 1080p, 2k, or 4k for MP4 video, you can't find the available option. As a program mainly designed for playing videos, VLC hasn't optimized its conversion function, which usually results in quality loss in the process.
