How this workspace works
- Choose an MP3, OGG or M4A file.
- Decode it in your browser.
- Download the uncompressed WAV file.
WAV files are uncompressed, so the result will be larger than an MP3 — that is expected and is what makes WAV easy to edit.
Your file never left this device, so there is no server copy to delete. Download again, start over, or continue with a related tool below.

Limits
Converting to WAV does not improve sound quality — it only preserves what the compressed original already had, in a larger file. Unsupported codecs fail honestly instead of producing a fake file.
