About this format

Audio in an MP4 container. Inside is usually AAC (lossy) or ALAC (lossless). The default for iTunes and iPhone, and fine on Android.

What it can hold

  • Audio (AAC or ALAC)
  • Tags and album art
  • Chapters

When you convert it

M4A → MP3If it was AAC, a little quality is lost. Compatibility becomes total.
M4A → WAVIf ALAC, lossless kept; if AAC, only larger.
M4A → AACJust strips the container. Same sound.

When it will not open

  • Old Windows Media Player
  • An ALAC m4a on a device that knows only AAC

In one line iPhone voice memos are m4a. If it will not open on a PC, convert to mp3.

Frequently asked questions

How do I convert a M4A file?

Drop the file into the window, pick the target format, and download the result. No account required.

Do I need to install anything?

No. It runs in your browser. A Windows installer is available separately if you prefer one.

What if the format I want isn't listed?

Every engine's capabilities are merged into a single graph, so unlisted pairs are chained automatically through intermediate formats along the least-lossy route.
