How to Convert M4A to MP3

Edited by Ben Jacklin

November 27, 2019

If you receive some music or an audio recording in the unfamiliar M4A format, don’t be concerned: it’s just a variation of the well-known MP4 or MPEG-4 format suitable for audio files with no video track. However, this MP4 variant is nowhere near as popular as its “big brother,” so you may encounter problems trying to play M4A files on your multimedia device or even your computer. The problem is easily solved by converting the M4A file into the standard MP3 format.

In this article, you’ll learn about 3 ways to convert M4A to MP3. You will also find a comparison table describing the differences between the two formats.

Frequently Asked Questions

An M4A file is an audio file stored within the MPEG-4 Audio container format. M4A audio files are typically encoded with the AAC codec, which is used for lossy audio compression.

It depends on the MP3 player you use. Normally, MP3 players support different audio formats, including M4A. If your player can’t open an M4A file, you can simply convert it to the MP3 format, which will be supported by your player. To convert M4A to MP3, try the Movavi converter. This powerful and easy-to-use app lets you convert audio files in no time.

With regard to the quality of the sound, M4A files are better than MP3s. M4A files are typically encoded with the AAC codec, which can provide the same audio quality as MP3, but at a higher compression rate. This means that M4A can achieve better sound quality compared to MP3 at the same file size and bitrate. M4A files can also be compressed with ALAC, which is a codec for lossless audio compression – in this case the quality will be much better, but the file size will be larger.

The advantage of MP3 is that this format is very popular and is supported by almost every device.

Samsung Music doesn’t support the M4A format, so you might need to convert your M4A files to a compatible format, like MP3, WMA, AAC, or FLAC. Try the Movavi converter to change audio formats quickly and easily. Alternatively, convert your M4A files online, for example, using Online Video Converter.

It depends on the codecs used in the file. M4A audio can be encoded with either AAC, which is a lossy compression format, or ALAC, which is used for lossless audio compression.
