How to Convert MKV to MP4 and Vice Versa

MKV is a popular format for HD video compression. However, in spite of becoming more popular over the last few years, it is still far from being widely supported on mobile devices and even computers as MKV files are often too “heavy” for smooth playback. There is an easy solution for this problem, though. You can transcode MKV video into an MPEG-4 file, which makes it possible to watch your movies and video clips on almost any platform or device.

With Movavi Video Converter, you can even transfer MKV to MP4 without losing quality using the revolutionary SuperSpeed mode! You can also use this smart app as an MP4 to MKV converter if you need to do the reverse – convert MP4 to MKV. The program was specifically designed for fast conversion between more than 180 multimedia formats, so you can forget about format compatibility problems once and for all.

Download Video Converter for Windows or Mac and give it a try – just follow the simple steps below and turn your files into a different format.

1. Install the Program on Your PC or Mac

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

2. Open Files for Conversion

First, add the files you want to encode into a different format: click Add Media in the upper left corner and select Add Video. Thanks to support for batch conversion, you can change the format of your whole video collection at once.

3. Select the Output Format

Open the Video tab to access the list of supported formats and choose the required format – MP4 or MKV – depending on your goals. Each format has a list of ready-made presets, offering a choice of resolutions. Select the one that best meets your needs. You can specify a custom resolution and other video parameters by clicking the cogwheel icon.

4. Specify the Destination Folder and Start Converting

By default, all output files are stored in the Movavi Library folder. If you want to use a different folder, click the folder button to the right of the Save to field and locate the required folder on your computer. To start processing your media files, just click the Convert button. Since the Movavi software supports the latest video processing technologies, conversion takes almost no time. No matter whether you transform your MKV files to MP4 or MP4 to MKV, the results will always be perfect!
