Convert AAC to WAV
Convert AAC to WAV on your device. Choose your file, convert, and check the result before sharing.
Drop the aac file
Drag your AAC onto the page or click to browse. It is read locally, never sent anywhere.
Choose WAV
WAV output is always 16-bit PCM, so there is no quality or bitrate menu. Click Convert to start processing in this tab.
Save the wav
The finished WAV downloads straight back to your device. Nothing touched a server on the way.
Why convert here, not there
No upload, ever
Your aac file is decoded and re-encoded by code in this tab - a song, a memo, a podcast never leaves the device.
Local conversion
No upload time for a big aac file, no server queue, no waiting on a download link.
No account, no daily cap
No daily caps, no "3 conversions left", no email wall. Convert the whole aac library.
The two formats, briefly
| AAC | AAC is a lossy audio codec. This page writes a standalone AAC file using the selected bitrate. | |
|---|---|---|
| WAV | WAV is a container commonly used for PCM audio. This converter writes 16-bit PCM; the source sample rate and channels are not deliberately changed. | |
When you need this
- Decode AAC for an editor or workflow that asks for WAV PCM audio. This output is 16-bit, not an enhancement of the original recording, and can be much larger than compressed audio.
AAC vs WAV: what changes
| AAC | WAV | |

| Typical size | Depends on the file and encoding settings. | Measure the exported file; it may be larger. |

Keep the original. Compare the exported file before sharing or replacing it.
Good to know
- WAV output here is 16-bit PCM. There is no bitrate choice; converting a higher-bit-depth source can reduce precision.
- First use downloads the audio/video engine (about 30 MB). The input cap is 2 GB, but available browser memory can run out below that.
