HOW TO CONVERT FROM MKV TO MP3 ONLINE?

Extracting an audio track from a video can be useful in some situations. This is particularly true if you have, say, a video recording of a live performance of your favorite band and you want to listen to the music separately without watching the video. The same applies to video lectures, podcasts, and seminars, where the sound is more important than the image.
The easiest way to extract the sound from your MKV file is to use our MKV-to-MP3 converter – an online tool for converting media files. It supports all popular video and audio formats and doesn’t take up space on your disk. It’s also safe – there’s no need to download potentially risky freeware on your PC. All you need to do is to follow this simple guide on how to convert MKV to MP3 online.
Add your MKV file.
Select MP3 as the target format.
Click Convert.

HOW TO CONVERT AN MKV FILE TO MP3 ON A DESKTOP?

If your MKV file is large, it’s best to use an offline editor. Try using SuperSpeed Video Converter to convert MKV to MP3 (free during the trial period). The software runs on both Windows and Mac.

Step 1.Install and Launch the Program

Download and install SuperSpeed Video Converter on your PC. When the installation is complete, launch the program.

Step 2.Add Your MKV File

Click Add Media, then Add Video, and select the MKV file you want to work with.

Step 3.Specify the Output Format

Click Audio, select MP3 as the target format, and choose a preset.

If you want to specify the properties of the output audio, click the Cogwheel icon, select Audio, and choose the bitrate. Remember that choosing a lower bitrate will result in a certain loss of quality. Click OK when you’re ready.

Step 4.Convert MKV to MP3

If you want to merge multiple tracks, turn on the Merge Files switch. Specify the folder in which the output file should be stored by clicking the Save to button. Then hit Convert. After the conversion is complete, the file will appear in the specified folder. This is how to change MKV into MP3 using the desktop program.

Both of these ways to convert files are easy to use; just decide which one you prefer depending on your needs.
