MP3 (MPEG-1/MPEG-2 Audio Layer 3) is a widely used lossy audio format. It shrinks file size by discarding partial original audio data irreversibly. It boasts universal compatibility, playable on nearly all audio players. Windows and macOS support native playback without extra software.
M4A is audio-only MPEG-4, while standard video-audio MPEG-4 files use the .mp4 extension. Most M4A files adopt lossy AAC encoding, and some Apple lossless tracks use ALAC. It’s common for DRM-free iTunes music downloads. It works natively on Apple devices, iTunes, and QuickTime. Windows Media players need extra codecs to open M4A files.

MP3 VS M4A
Typically, M4A is perceived as the successor to MP3, and they have some common points. For example, they are designed to download audio and use the compression mechanism to impact the size of the music. Additionally, they also have some differences, and you may ask which one is better. Now, let’s keep reading.
- Video Quality
- Compatibility
1. Quality
Compared to MP3, the M4A file with ALAC codec has better original sound quality and even an M4A file with AAC codec offers better quality at the same bit rate. This is because M4A features a large bit rate. Besides, file size is also related to the bit rate. The larger the bit rate, the larger the file size and the better the sound quality. But this doesn’t mean the sound quality of the MP3 file is poor but M4A is better.
2. Compatibility
M4A is a limited audio format file and some of the devices don’t support it and M4A cannot be shared on other devices. In short, its compatibility is not good. While MP3 allows sharing across other devices and the file can be used on multiple devices.
To sum up, if you want to listen to music with high quality on Apple devices, M4A is recommended. If you prefer compatibility, MP3 is suggested. No matter whether you are using MP3 or M4A, these two file formats can be converted to each other.
