M4A is the extension of the standard MPEG-4 audio file. Since Apple began using M4A in its iTunes and iPods to distinguish the video and audio files from MPEG-4, the M4A extension has become popular. But M4A is an audio format compatible with Mac. If you need to play it on Windows, Samsung, Android LG, HTC, or other systems, you may meet some knotty troubles.

Whereas MP3 is a sought-after audio format that can be recognized by most devices and players. To play M4A anywhere, you’d change it to MP3. How to convert M4A to MP3 on Mac with the easiest ways? Here shows the ultimate guide.


How to Convert M4A to MP3 on Mac Free with iTunes

In terms of audio quality and file size, M4A indeed has a greater advantage over MP3. But if we are unable to play the M4A file, all the advantages are just decorations. So changing M4A to MP3, you will have no worries about the M4A audio playback problem.

In this part, you will know how to convert M4A to MP3 on Macintosh with iTunes - the app preinstalled in macOS Mojave and earlier.

  1. Launch iTunes. Click the tab in the upper banner, navigate to "iTunes" > "Preferences" > "General".convert m4a to mp3 with itunes 01
  2. In the "General" interface, click on “Import Settings…”.
  3. Choose "MP3 Encoder" from the dropdown menu of "Import Using". Click OK.convert m4a to mp3 with itunes 02
  4. Select an M4A song that you want to handle and right-click the song to bring up a menu. Choose “Create MP3 Version” to save your M4A songs to MP3 format in iTunes on your PC.

Although this method requires only a few clicks to complete the conversion, it is not my most recommended method. Because iTunes only provides users with limited output audio formats. Meanwhile, since macOS Catalina, iTunes separates into Apple Music, Apple TV, and Apple Podcasts.

Apart from iTunes, we can still use other useful converters to start the conversions. Here we list 6 tools to help you.

It is able to convert 200+ audios and videos, and it even supports loading files from iTunes directly for conversion. However, it can only convert M4A to MP3 for free without additional decoration.

#3 Audacity (open-source audio editor and recording app)

Audacity was initially unable to import M4A, because it could only add some common audio file formats like WAV, AIFF, and MP3. If you have the FFmpeg library installed, it will support more formats, including M4A, AC3, MP4, WMA, etc. Audacity uses LAME to encode MP3, and it actually has been packed with a built-in LAME encoder already. But you can still install a higher version. These two extra libraries are necessary for converting M4A to MP3 but are not packaged together.


  1. Free and open source
  2. Support bulk conversion
  3. Can also edit the audio effects and record screen


  1. Need to download third-party tool
  2. Not friendly to people because of the outdated interface without any prompt


  1. Navigate to https://lame.buanzo.org/#lameosx64bitdl. Find the FFmpeg package you need to download to your Mac.
  2. Download and install FFMPEG.
  3. Launch Audacity. Go to the menu bar, and click on “Audacity” > “Preferences” > “Libraries” > locate and add the FFmpeg library.convert m4a to mp3 macintosh audacity 01

  6. Edit metadata tags and click “OK”.

Note: If you want to use Audacity to batch convert M4A to MP3 free on Mac without mixing them into one stereo file, just add all M4A files to the interface, click “File > Export > Export Multiple” when making the output settings. After choosing MP3 as the output format, click “Export” and then edit metadata tags for each file one by one. After editing the last one, click “OK” to start the conversion.

#4 Terminal (use command line and FFmpeg)

Terminal provides a graphic interface for some transcode programs, like FFmpeg, using the command lines to make different conversions. It's complicated to make conversions on Mac in the terminal. It will cause "command not found" because of outputting a character or letter. It took me a lot of attempts to get it right, which was a bit time consuming, especially for beginners.

  2. Support batch conversion


  1. Need to remember different command lines for different file format conversions
  2. Need to help of third-party conversion tools


  1. Install FFmpeg and open Terminal.
  2. Type the command line.
    To convert a single M4A file to MP3, use the one of the commands: ffmpeg -i input.m4a output.mp3, ffmpeg -i input.m4a -acodec libmp3lame output.mp3, ffmpeg –i input.m4a -f mp3 output.mp3.convert a single file ffmpeg To convert multiple M4A files to MP3, create a folder on the desktop to save M4A files and enter the script: for i in *.m4a; do ffmpeg -i "$i" "${i%.*}.mp3"; done.
  3. Press the enter key to start to convert M4A to MP3 free with FFmpeg on Terminal.

You can't type the command line: ffmpeg -i audio.m4a -c:a copy audio.mp3 to copy or remux M4A to MP3, as they use different codecs.


#5 Automator (self-service engine and automation tool)

The Automator app built into macOS is a way to create workflows for handling repetitive manual tasks and boosting efficiency. If you need to convert audio files to MP3 often, Automator can help you save and reuse your workflows, along with creating MP3 in bulk. The custom scripts below are written in Automator using Shell to convert M4A to MP3 on Mac.


  1. Can auto complete repetitive tasks
  2. Work with various third-party programs on Mac, like Safari, Finder and more


  1. Not user-friendly


  1. Open Automator. Go to “File” > “Services”, and click “Choose”.go to service

1) Can I convert M4A to MP3 on Macintosh via Google Drive?

  1. Sign in to your Google Drive.
  2. Import the M4A file.
  3. Open M4A with “CloudConvert”, and then perform the conversion there.open m4a google drive

2) Can I convert M4A to MP3 on Mac using QuickTime?

The answer is no. QuickTime merely allows you to export media files to M4A format now.

Whether it’s the past or the present, the answer is no.

The old version of QuickTime 7 Pro allows you to export media files to AIFF, AU, and Wave. There are no MP3 options to choose from. The sole solution is to install a third-party add-on (LAME encoder).

However, QuickTime Player 7 no longer provides Pro upgrades since 2009 and Apple has completely killed it since Catalina.

When Mac OS X Snow Leopard was released, it's equipped with the new QuickTime X Player, which can merely save the audio to M4A format.

3) Can VLC change the M4A file to MP3 on Mac?

Yes, VLC offers an audio transcoding function. You should select the format as "Audio-MP3" and make sure to manually name the file as "xxx.mp3". It seems to me that VLC on Mac isn't as good as it is on Windows, as the latter supports more plugins, update timely and is more flexible.



We introduced 7 ways to convert M4A to MP3 on Mac. Taking into account the limitations of the iTunes application, audio-only converter and online converters, as well as the complexity of Audacity, the command line, and Automator, we are more inclined to use the full-featured applications, like Cisdem Video Converter for Mac. You can easily find the merits of it.
