How to Convert M4A to MP3 on Windows 10/11 (Best Quality)

Edited by Cecilia Hwung | Last Update:

Files with the .m4a extension are often seen in Apple Music downloads, iPhone Voice Memos, and audiobooks and podcasts sometimes. M4A represents MPEG-4 files with only audio streams and uses AAC (Advanced Audio Coding) and ALAC (Apple Lossless Audio Codec) to encode the file.

M4A AAC is a lossy format supported by Windows, Mac, Linux, iOS, and Android. But M4A ALAC does not fit other platforms very well outside the Apple ecosystem. Besides, M4A ALAC is larger and needs more data and space to transfer and store due to the lossless codec.

To solve the problems above, try to convert M4A to MP3, a universal audio format for Windows Media Player, iTunes for Windows, or other apps on your device. Here we'll show you 7 ways to convert M4A to MP3 on Windows (11/10/8.1/8/7), as well as some tips for keeping the original sound quality.

2. How to Convert M4A to MP3 in Windows Media Player

Before Windows Media Player 12, the "Save as" button allowed you to convert videos and audio files to MP3 easily. But now, this feature is greyed out and media conversion becomes a little bit tricky.

If you want to convert M4A to MP3 using Windows Media Player, prepare a blank CD in advance, and then follow the instructions below.

Step 1. Open Windows Media Player and load your M4A file to it.

Step 2. Insert a blank CD into your Windows PC. Open the Burn tab on the right side. Expand Burn options and select Audio CD.

Step 3. Add the .m4a file to the burn list. Click Start burn and wait for it to complete.

Step 4. Open Organize > Options > Rip Music, set the format to MP3, and choose a file location. Click Apply and OK to start converting M4A to MP3 in Windows Media Player.
