Upload a M4A file, choose an output such as 3GP, AAC, AIFF or ALAC, and download the result. M4A is an MPEG-4 audio file, usually containing AAC (lossy) or sometimes ALAC (lossless) audio.
A M4A source is an MPEG-4 audio container commonly holding AAC audio plus tags and cover art. Its useful destination depends on which stored properties the receiving workflow actually consumes.
Related formats: the AAC audio format conversion options and the MPEG Layer III audio conversion options cover neighbouring jobs.

Confirm the specific program, device, or platform on the other end before picking an output format.
The codec, sample format, bitrate, channels, and metadata all change during audio conversion, sometimes invisibly. What counts as an acceptable result differs for a studio master, a delivery copy, and plain speech.

Players may support M4A but reject a particular codec, and cover art or chapter metadata can be dropped.
Confirm codec compatibility, duration, gapless playback, tags, and album artwork.
