What is M4A?

The M4A file is short for MPEG-4 Audio, and not to be confused with MP4 or MP3. Apple developed M4A as a file container for audio media, including songs, audiobooks and podcasts. Compared to MP3s, M4As have better sound quality — but they also have larger file sizes than MP3s. M4A files can only store audio as well, unlike MP4 files which can store audio and video.

To play an M4A file, you can use Apple Music, iTunes, Windows Media Player, VLC and more.

What is MP4?

MP4 is one of the most widely used video file formats. You can upload MP4 videos to popular social media sites like YouTube, Instagram, TikTok, Twitter and Facebook. Media players like Windows Media Player, VLC, QuickTime, iPhone, iPad and Android are also compatible with MP4 video files.

MP4s are popular not only for their compatibility with most devices but also for their ability to hold high-resolution videos without taking up much storage space. MP4 stands for MPEG4, and an MP4 file can contain video, audio, images and subtitles.
