About this format

Lossy compression created in 1997 as mp3's successor. Better than mp3 at the same size; used by YouTube, iTunes and broadcasting. Usually found inside an m4a or mp4.

What it can hold

  • Audio (lossy, more efficient than mp3)
  • Multichannel

What it cannot

  • Tags — raw aac carries titles poorly. Wrap it in m4a

When you convert it

AAC → MP3A little quality lost; opens anywhere.
AAC → M4ANothing lost; tags become possible.

When it will not open

  • Some players cannot open raw .aac — wrapping it in m4a fixes that

In one line Keep aac wrapped in m4a. Same sound, opens everywhere.

Frequently asked questions

How do I convert a AAC 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.
