How do I convert an AAC file to M4A?

Upload your AAC file to our converter, select M4A as the target format, and click Convert. The tool remuxes the audio stream into an M4A container, preserving the original codec and bitrate. Download the resulting .m4a file instantly.

Why should I convert AAC to M4A instead of keeping the original AAC file?

M4A is Apple's preferred container format and is widely supported across iTunes, iOS devices, and macOS. It stores AAC audio with better metadata support, cover art, and gapless playback. Converting AAC to M4A ensures maximum compatibility with Apple products and modern media players without changing the audio quality.

Will converting AAC to M4A affect the audio bitrate or codec?

If your AAC file uses a supported codec (e.g., AAC-LC or HE-AAC), the converter performs a lossless remux: it copies the audio bitstream into the M4A container without re-encoding. That means bitrate, sample rate, and channel count remain identical. Only an unsupported format might trigger a re-encode, but our tool always selects a lossless mapping when possible.
