How to convert WAV to M4A (AAC)

  1. Choose or drop one WAV file up to 100 MB.
  2. Select the output quality. The balanced default works well for most files.
  3. Start the conversion and keep this tab open while the browser processes the audio.
  4. Download the verified M4A (AAC) result.

What this conversion creates

The output is a real M4A (AAC) file encoded as AAC-LC. AudibleLite runs a bundled WebAssembly audio engine locally; it does not rename the extension or send your audio to an application conversion server.

When this format helps

AAC in M4A is a practical choice for mobile devices and media libraries that favor the MP4 family.

The result contains AAC-LC audio in an M4A container and works with common modern players.

Quality and file-size limits

AAC is lossy. Keep the original WAV if you need an uncompressed master.
