Step 2. Select MP3 as output format

Click on the blue format icon, a format tray will pop up. Choose “MP3” from the “Audio” tab.

For further configuration, click the "gearwheel" icon next to the output option you choose. And then a "Setting" window will display, which gives you an opportunity to adjust the parameters of the exported audio.

Note: If you are not a technical user, keep the current settings, which are already good enough.

Step 3. Convert M4A audios to MP3 on Macintosh

Select a folder as the output path in "Save to". In the end, click the icon to start the conversion of M4A audio to MP3 on Mac without degrading the original quality.

 

#2 To Audio Converter (a dedicated audio-only converter app)

To Audio Converter is a simple yet helpful audio converter that focuses on generating audio files in MP3, M4A, FLAC, AIFF and WAV format. 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. If you want to edit the files or make bulk conversions, you have to upgrade to its premium version.

Steps:

1. Download and install the program on your Mac.
2. Open it, clear the “gearwheel” icon on the default interface to make output settings.
   
3. On the popped-up window, stick on the Format section, click the drop-down icon of “Audio Format” box to select “MP3 (MPEG Audio Layer 3)” option. Also, you can change other settings based on your needs.
   
4. Back to the main interface, if needed, click “Destination” button to choose a suitable location so that you can easily find the converted file.
5. Finally, tap on “Open” button to choose the M4A file for conversion, or directly drag-n-drop the target M4A to the program to start the conversion. Meantime, it will pop up a new window for you to view the working process.

 

#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.

Steps:

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.
4. Return to the main interface of Audacity. Drag-n-drop M4A audio into it.
5. Head to “File” > “Export” > “Export as MP3”. From the pop-up “Extract Audio” window, click “Save”.
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 command-line programs, like FFmpeg, enabling you to transcode between different file formats. But it's complicated to make conversions on Mac with FFmpeg in the terminal. It will cause "command not found" because of outputting a single character or letter incorrectly. It took me a lot of attempts to get it right, which was a bit time-consuming, especially for beginners.

Steps:

1. Install FFmpeg and open Terminal.

2. Type the conversion command line.

To convert an individual M4A file to MP3:

1) Type cd location, e.g. cd Desktop, and hit the Enter key to specify a folder to store your output MP3.

2) Use one of the following commands:

• ffmpeg -i input.m4a output.mp3
• ffmpeg -i input.m4a -acodec libmp3lame output.mp3
• ffmpeg –i input.m4a -f mp3 output.mp3

To convert multiple M4A files to MP3:

1) Create a folder to save M4A files.

2) Type the folder location, for example, on my Mac, it’s cd /Users/test/Desktop/M4A. Press Enter.

3) Type the script: for i in *.m4a; do ffmpeg -i "$i" "${i%.*}.mp3"; done.

3. Start converting 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.

Steps:

1. Open Automator. Go to “File” > “Services”, and click “Choose”.
2. Choose "audio files" in services receives selected and "Finder" in any application.
3. Search for "Run Shell Script" in the "Library" on the left and drag it to the right.
4. Choose "/bin/bash" in Shell and "as arguments" in Pass input.
5. Change echo "$f" into /Users/thh/Downloads/ffmpeg -i "$f" "${f%.m4a}.mp3" in script. Replace /Users/thh/Downloads/ffmpeg to your own path.
6. Navigate to “File” > “Save”. Put "convert to mp3" in the service name and save it.
7. Locate to the M4A files you wish to convert. Right-click on them and choose “convert to mp3 ”.

FAQs

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.

Can I convert M4A to MP3 on Mac using QuickTime?

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.
