How to Convert M4A (AAC) to MP3

M4A (AAC) is the default format for iTunes purchases and iPhone voice memos. While it sounds great, some devices and older software don’t support it. Converting to MP3 makes the files universally compatible without noticeable quality loss at high bitrates.

Step 1 - Add your M4A files

Start MDHM Audio Converter, then either click the + button or drag and drop files directly into the window. You can add multiple files at once.

Step 3 - Set quality

Choose from predefined quality presets or select Custom to set the exact bitrate. For music, 256-320 kbps gives a good result.
