  2. Convert it to .AAC in a few seconds.
  3. Download your new .AAC file.

What to expect

  • Only the audio is kept; the video stream is discarded, producing an audio-only file.
  • The audio is re-encoded to AAC (lossy), so quality cannot exceed the original track.
  • AVI metadata and any additional streams are not carried into the single AAC audio file.

Frequently asked questions

What do I get when I convert AVI to AAC?
You get the audio track only, encoded as AAC; the video is discarded entirely. The result is an audio file, not a video.
Does the audio lose quality?
The AVI's audio is re-encoded into AAC, a lossy format, so some fidelity is lost, and quality is capped by the original track. A higher bitrate keeps the loss small.
Why convert AVI to AAC?
Extracting audio to AAC gives a compact, widely supported sound file for music players and mobile devices, useful when only the soundtrack of an AVI is needed. AAC is broadly compatible and efficient.
Where does an AAC file play?
In VLC, Windows Media Player on Windows 10/11, and the Music app on Apple devices, among many others. AAC is a widely supported audio standard.
