Download the installation file for Movavi Video Converter to your hard drive, open it, and install the program.

Locate the files you want to convert on your device by clicking Add Media in the upper left corner, selecting Add Video, and choosing the video or videos that you want to convert. If you want to use SuperSpeed Conversion, your MKV files will need to be encoded with H.264 or MPEG-4 codec. Without these file formats, you cannot use SuperSpeed mode for your video conversion.

Open the Video tab and find the icon associated with the format you want to use. Since you want to convert MKV to MP4 on a Mac, you will want to select the MP4 icon. You will then see a list of MP4 formats. Choose the one that best meets your needs. The preset with the SuperSpeed icon will convert fastest, allowing you to view your video more quickly. As you convert your MKV to MP4 on your Mac, however, make sure that you choose the format that best fits your needs.

By default, all converted files are stored in the Movavi Library folder. If you want to use a different folder, click Save to and locate the desired folder on your computer. Click the Convert button to start the process. Since the Movavi app supports one of the fastest video processing technologies, your files will be converted in no time.

Select File, then choose Convert/Stream. Click the Open Media button to upload your file. Choose the MKV file that you want to convert to MP4 format. You can also drag and drop files onto the list, which can prove more convenient if you have the file list open in another location.

In the Choose Profile section, select Video– H.264+ MP3 (MP4). Click the Customize button if you want to edit the selected profile.

To upload your video, click the Add Your Media button and locate your MKV file.

You will need to select MP4 as your intended end file type for the conversion. To do this, just open the Convert to drop-down menu and find MP4 from the list.

Click the Convert button to start the conversion process. Once you have converted your MKV file to MP4, the file will be downloaded automatically. Again, this may take some time, depending on the length of the file.

▶️ What is an MKV file?

The MKV file format is a common multimedia file. It contains video and audio content in one easy file, which makes it easier for others to view. The MKV file type supports high-quality H.264 video. MKV files are very large file formats, which can make them unwieldy. While they offer an excellent viewing experience, they may be difficult to watch in some formats, including on mobile devices and Apple computers.

MKV files are very large-format files. If you're trying to convert an MKV file, it probably hasn't taken you long to figure out that the format is very large – especially if you've attempted to perform that conversion online. The codecs used for the content inside the MKV file take up a great deal of space. In short, these large files are the price you pay for high-quality video playback. It's important to take that into consideration, both as you're deciding what format you want to use for your videos and as you're evaluating what steps you need to take when converting your MKV videos.

▶️ What is the MKV format used for?

MKV (which stands for Matroska Video) is a universal format designed as a new standard for high-quality video compression. MKV can combine HD video with multiple audio tracks and subtitle tracks – that’s why it is a good choice for storing movies, TV shows, and concerts.

▶️ Can I play MKV files on a Mac?

Unfortunately, Mac users may encounter difficulties when viewing MKV files, and iPhones do not support MKV at all. To open MKV files on Apple hardware, you need to convert MKV to a more common format, for example, MP4. The best way to do this is to use a dedicated conversion program. Movavi Video Converter can help you transform your files fast, thanks to its SuperSpeed mode.

▶️ Can MP4 files be played on a Mac?

Although Mac’s default player supports the MP4 video format natively, it can only play files compressed with MPEG-4, MPEG-2, and H.264 codecs. If you want to play an MP4 file encoded with a different codec, you’ll need to install a player that supports that codec, or convert the video clip to another format, like MOV.

▶️ Is MKV better than MP4?

Which format is better – MKV or MP4? Both MKV and MP4 are popular video formats that support H.264 video. However, Apple smartphones and Mac computers don’t support MKV natively, while MP4 is a default format for iPhone, iPad, and many other devices. So, if you want to transfer videos to your iPhone, it’s better to choose MP4, but if your device supports MKV, you can keep your files in this format.

▶️ Will converting MKV to MP4 reduce the file size?

Yes, it will help to make the file smaller. MKV files are usually larger than MP4s because of some attributes like multiple tracks and subtitles. A smaller file size means quicker downloads as well as savings in storage space. So if you need your MKV video to be smaller, try converting it to the MP4 file format. If you’re worried about quality loss, use the Movavi MKV-to-MP4 converter for Mac – it enables you to change the format of your videos while retaining good quality.

▶️ How do you play MKV files on an iPhone?

iPhone doesn't support MKV natively, but you can use third-party media player apps that will either play or convert MKV files. The best option is to usually convert MKV files using a desktop or an online tool.

▶️ How can I import MKV to iMovie?
