What is a M4A file?

M4A stands for MPEG-4 Audio and is a popular audio format used for storing compressed audio files. Unlike MP3, M4A files often use AAC encoding, which provides better sound quality at similar file sizes. It was developed by Apple and is widely used in iTunes and iOS devices.

M4A files are typically used for music and podcasts, offering high efficiency and compatibility with modern players. Since they don't support digital rights management (DRM), they are preferred for unrestricted distribution of audio content.

How to open M4A files

M4A files can be opened with iTunes, QuickTime, VLC Media Player, and most smartphone music apps. They’re fully supported on macOS, iOS, and many Windows players.
