How to make an MP4-to-MP3 Conversion

Edited by Ben Jacklin

September 19, 2019

MP4 or MPEG-4 is currently one of the most popular multimedia formats. Because of the optimum balance between video size and quality, MP4 is used for multiple purposes: encoding large movies or TV episodes, online video streaming such as YouTube clips, and even for audio files. However, if you only need the soundtrack, there’s no need to keep the video component; you can just convert your video to, for example, an MP3 audio file. MP3 is supported by almost all devices and players, so you’ll be able to enjoy the sound anywhere. There are a number of situations in which you might want to extract audio from video.

You like a movie and want to keep the soundtrack

Sometimes it is tough to separate out a soundtrack in a video even with special software, and converting the video file to an MP3 audio may help. This method also works when you like a movie soundtrack: you can even extract a single song with the built-in trim tool.

You only need the audio from a large video file

Concerts, lectures, business training, even entertainment programs are often available just like videos. If you want to have the opportunity to re-listen to them from time to time (e.g., when you’re on your way somewhere), convert MP4 to MP3 and access the audio whenever you want.

You’d like to make an audiobook from a cartoon

If your children like cartoons, why not convert those videos into MP3 audio books? Kids will enjoy listening to their favorite movies. These audio files can be used instead of a lullaby or a bedtime story. You can also take an MP3 player with these audio books loaded to entertain your child on a long car trip.

There are several approaches to the file converting. Click one of the links below to get to the section needed.

How to Convert MP4 to MP3

Converting MP4 to MP3 is very easy. All you need is Movavi Video Converter for PC or Mac with support for almost all known media formats and many other benefits. Take any music video and easily turn it into an audio track. To learn how to do this the right way, take a look at our short step-by-step instructions.

Before you start, download Movavi’s MP4-to-MP3 converter and try it completely free!

Install the Movavi Software

Once you have downloaded Movavi Video Converter, simply double-click the downloaded file to start the installation and follow the on-screen instructions. Wait a few seconds until the process is complete and then run the program.

Add Files for Conversion

Click Add Media and then Add Video (or Add Audio if you want to convert MP3 to MP4) to open the files you need to encode, and then add them to the program. You can also add the files by simply dragging them from their folder into the converter window.

Choose the Output Format

Click Audio in the bottom part of the interface and find the MP3 preset group. Click it and choose your preferred bitrate options. Remember that the higher the bitrate, the better the quality; however, higher quality audio files will also take up more disc space, even with MP3 files.

In the converse case of transferring MP3 to MP4, switch to the Video tab and select one of the MP4 presets.

Set a Target Folder and Start the MP4-to-MP3 Conversion

Hit the Save to button to specify the target folder in which you want to save your files or they will be saved in the default Movavi Library folder. Click Convert to start the conversion. Once the job is done, the folder containing your music files will open automatically.
