How to Convert M4A to MP3 on Mac and Windows (2026 Guide)

"Need some help to convert M4A to MP3? I have a lot of recordings on my iPhone saved as .m4a files, but some devices or players won't recognize them. How can I convert M4A to MP3 quickly and safely?"

M4A is a common audio format used by Apple, typically encoded with AAC or ALAC, offering good sound quality and efficient file size. It works well within modern apps and Apple devices, but MP3 remains the most universally supported format across older players, car stereos, and various platforms. That's why many users look for ways to convert M4A to MP3 for better compatibility.

In this guide, you'll learn how to convert M4A to MP3 on Mac, Windows, and online using simple and effective methods, whether you want a quick one-time conversion or batch processing for multiple files.

Method 1. Convert M4A to MP3 on Mac with Apple Music

If you're using a Mac, the easiest way to convert M4A to MP3 is by using the built-in Apple Music app. This method requires no extra downloads and is ideal for users who want a quick and reliable way to convert local M4A files to MP3.

It works best for occasional conversions or small batches, especially when your audio files are already stored on your Mac. However, keep in mind that it may be slower for large-scale batch conversions compared to dedicated tools.

Step 1. Open the Music app on your Mac, then go to "Music > Settings > Files > Import Settings".

Step 2. Choose "MP3 Encoder" from the “Import Using” dropdown and click "OK".

Step 3. Add your M4A file to the library (drag and drop if needed), then select the file.

Step 4. Click "File > Convert > Create MP3 Version" to convert the M4A file to MP3.

Method 2. Convert M4A to MP3 with VLC on Windows/Mac

VLC Media Player is a free and open-source tool that can do much more than just play media, but also serves as a reliable M4A to MP3 converter on both Windows and Mac. If you already have VLC installed, this is one of the easiest ways to convert M4A to MP3 without using online tools or installing additional software.

This method is ideal for users who want a completely free, offline solution. It supports basic batch conversion and works well for most local audio files, though the interface may feel less intuitive compared to dedicated converters.

Step 1. Open VLC Media Player, then click "Media > Convert/Save" on Windows, or "File > Convert/Stream" on Mac.

Step 2. Click "Add" to import your M4A file, then click "Convert/Save".

Step 3. Under "Profile", select "Audio – MP3" as the output format.

Step 4. Choose a destination file name, make sure it ends with ".mp3", then click "Start" to convert.

Method 3. Convert M4A to MP3 with Audacity on Desktop

Audacity is a free and open-source audio editor available on Windows and Mac. It's a powerful option if you want more control over audio quality when converting M4A to MP3, such as adjusting bitrate or handling multiple files at once.

Unlike VLC, Audacity requires an additional setup step to work with M4A files. You'll need to install the FFmpeg library to enable M4A import and export. Once configured, it becomes a flexible solution for both single and batch M4A to MP3 conversion.

Step 1. Install Audacity on your computer, then install the FFmpeg library if prompted.

Step 2. Open Audacity, go to "Edit > Preferences > Libraries", and click "Locate" to link FFmpeg (if not automatically detected).

Step 3. Drag and drop your M4A file into Audacity.

Step 4. Click "File > Export > Export as MP3", choose your desired quality settings, and save the file.

Method 4. Convert M4A to MP3 Online via CloudConvert

If you prefer not to install any software, online tools like CloudConvert offer a quick way to convert M4A to MP3 directly in your browser. This method is especially useful for one-time conversions or when you're using a shared or mobile device.

However, compared to desktop tools, online converters may have limitations in file size, batch processing, and speed. They also rely on an internet connection, so they are less suitable for large files or frequent conversions.

Step 1. Go to CloudConvert. Hit the "Select File" button to choose your M4A files.

Step 2. Choose MP3 from the "Convert to" drop-down menu. Click the wrench icon to adjust the audio scale, audio bitrate, channels, and more based on your preference.

Step 3. Click "Convert" to start M4A to MP3 conversion. Finally, you can preview the output and download the converted file by clicking the "Download" button.

While CloudConvert offers a viable solution, free accounts can convert files up to 1GB in size with only no more than 25 audio files per day. For unlimited M4A to MP3 conversion, it is better to consider other options.

Bonus: Convert Protected Apple Music M4A Tracks to MP3

If your M4A files come from Apple Music, you may notice that the methods above don't always work. That's because Apple Music tracks are managed differently from regular local audio files, even though they may also use the M4A format.

In this case, instead of converting existing files, you may need a tool that can process Apple Music tracks and save them as MP3s for offline use on different devices. Tools like TuneFab Apple Music Converter are designed for this specific scenario, especially if you want to export playlists or multiple songs at once.

Step 1. Select Apple Music as the Source Service

Launch TuneFab Music Converter, and then select Apple Music in the main interface. Next, log in to the built-in Apple Music web player with your account. Otherwise, you can't access the full library.

Step 2. Add Apple Music to Convert

Browse the Apple Music library to find your favorite songs and drag them to the "+" icon on the right, or click the floating "Add to Convert" button directly. TuneFab will automatically fetch music information.

Step 3. Select MP3 as the Output Format

In the conversion list, you can simply customize the output format, sample rate, and bitrate of each song. Here, click on the "Convert all files to" menu on the upper right to select MP3 as the output format.

Step 4. Convert Apple Music M4A to MP3

Hit the checkbox to select your wanted music tracks to convert. Then, simply click the "Convert Now" button to start converting Apple Music to MP3. After that, you can move to the "Finished" tab and hit "View Output File" to locate all your downloads on your PC. Now, you successfully convert M4A to MP3 on Windows/Mac.

FAQs About Achieving M4A to MP3 Audio Conversion

M4A vs. MP3: Which One Is Better?

M4A and MP3 are both widely used audio formats, but they serve different purposes. M4A (usually encoded with AAC or ALAC) often delivers better sound quality at a similar or smaller file size, making it a good choice within modern apps and Apple devices. MP3, on the other hand, is more universally supported across devices, including older players, car systems, and various platforms. If compatibility and easy sharing are your priorities, converting M4A to MP3 is usually the better option.

What Is the Free Program to Convert M4A to MP3?

There are several free ways to convert M4A to MP3 depending on your needs. On Mac, you can use the built-in Apple Music app for simple conversions.

The best choice depends on whether you prefer convenience, advanced settings, or batch processing.
