M4A to AAC Converter - free, no upload

Convert M4A to AAC

M4A already contains AAC audio; this pulls it out into a bare AAC stream rather than an MP4 container. Some hardware players and older tools want the raw stream and choke on the container.

What is M4A?

AAC audio in an MP4 container, which is what iTunes ripped to and what most podcast apps hand you. It sounds better than MP3 at the same bitrate. It's also the file that gets refused by car stereos and upload forms often enough to keep this converter busy.

What is AAC?

MP3's designated successor and the audio in most video - YouTube, streaming services, broadcast, virtually every MP4. At a given bitrate it beats MP3 audibly, especially below 128kbps, and every phone and browser decodes it.
