Convert Audio to WAV
Also known as: Convert to WAV File
Convert MP3, AAC, OGG or any browser-playable audio file to WAV.
Choose a file or paste
Files never leave your device — this runs entirely in your browser. Output is WAV.
Know what your WAV download contains
16-bit PCM audio
Choose a file, then press Convert to WAV. The download contains uncompressed 16-bit PCM samples using the decoded audio’s channel count and sample rate. It does not copy source tags or cover art.
Decoding depends on your browser
The input limit is 100 MiB (104,857,600 bytes). A file must also be decodable by your browser; its extension alone is not enough. Decoding can use much more memory than the file size. There is no sample-rate picker, and converting a lossy source does not restore lost detail.
Audio conversion stays on your device
The selected audio is decoded and encoded in the browser. The WAV download is created locally; the audio is not uploaded for conversion.
Estimate an uncompressed file
10 seconds of decoded stereo audio at 48,000 Hz16-bit PCM needs 10 × 48,000 × 2 × 2 = 1,920,000 sample bytes, plus the 44-byte WAV header. The result can be much larger than the compressed input.

FAQ
- Does converting to WAV improve the audio quality?
- No — WAV is lossless, but it cannot restore detail a lossy source (like MP3) already discarded. It just re-encodes the decoded audio without further compression.
- Why is the WAV file much larger than my original MP3?
- WAV stores uncompressed 16-bit PCM samples, while MP3 is compressed — a 3-4 MB MP3 can easily become a 30-40 MB WAV.
- Does this tool upload my audio anywhere?
- No — decoding and encoding both happen locally in your browser.
