About Audio to WAV
WAV stores raw, uncompressed PCM audio, which makes it the safest format to drop into a video editor, DAW, sampler or speech tool. This converter decodes your file and writes a standard 16-bit PCM WAV that virtually every audio program can open.
When it helps
- Importing an MP3 or M4A into an editor such as Audacity, Premiere or a DAW that prefers uncompressed input
- Preparing audio for transcription or speech-recognition tools that ask for WAV
- Loading clips into hardware samplers, drum machines or soundboards that only read WAV
- Decoding a FLAC file for software that doesn't support FLAC
Tips
- Expect WAV files to be large: CD-quality stereo takes roughly 10 MB per minute, many times the size of an MP3.
- Converting an MP3 to WAV does not improve its sound. It just stores the already-decoded MP3 audio without further loss, which is useful when you plan to edit and re-export.
- The output is 16-bit. If you have a 24-bit studio master you need to keep at full depth, use FLAC or keep the original.
- The bitrate slider has no effect here because PCM is uncompressed.

No. The WAV is a lossless copy of the decoded MP3, but the detail the MP3 encoder discarded is gone for good. The benefit is that further editing won't add another round of lossy compression.
WAV is uncompressed, so every sample is stored in full. A 4 MB MP3 song can easily become 40 MB or more as WAV.
Yes. There is no sign-up, no watermark and no limit on how many files you process.
No. Files are read and processed locally in your browser, so they never leave your device.
