About M4A
M4A is an audio format commonly used by Apple devices and many modern apps. It most often stores AAC-compressed audio, though Apple Lossless (ALAC) can use the same extension. AAC typically delivers strong quality at smaller file sizes than uncompressed WAV.
M4A works well for music libraries, podcasts, and mobile playback. It is a solid choice when you want high-quality audio that still fits comfortably on phones and tablets.
Fun fact: M4A is part of the MP4 family of formats, even though it is used mainly for audio rather than video.
Why Convert WAV to M4A?
Converting WAV to M4A shrinks large uncompressed files into a more efficient AAC-based format without giving up strong listening quality. M4A is especially convenient for Apple devices and modern media libraries.
Choose M4A when you want smaller files than WAV but better efficiency than older compressed formats.
How to Convert WAV to M4A
Select your WAV files, open Settings to adjust quality if needed, and click Convert. Your M4A download will be ready in seconds.
