Use this AAC to WAV converter to turn AAC files into WAV right in your browser — ideal for recording and editing, studio-quality audio and source masters. AAC uses lossy compression and WAV uses no compression, so file size and quality can change.
When should you convert AAC to WAV?
- When you need it for recording and editing
- When you need it for studio-quality audio
- To open your files in apps that prefer WAV
- To share WAV files more easily
What happens to your file
The AAC audio is decoded and re-encoded to WAV with PCM signed 16-bit little-endian at uncompressed. There is no video stream involved, so the job is quick even for long recordings.
Settings this conversion runs with
| Engine | ffmpeg |
|---|---|
| Output codec | PCM signed 16-bit little-endian |
| Setting | uncompressed |
| Compression | Lossless |
What changes
- WAV is lossless, but it can only preserve what is already in the AAC file. Detail removed when the AAC was first encoded does not come back — you get a bigger file of the same audio, not a better one.
- Cover art, lyrics, and most tags are not carried across — the output keeps the audio, not the metadata around it.
