How it works

- ConvertThe sound is unpacked into a WAV file, with nothing added or changed.
- Download the WAVOpens in every audio editor, sampler and recording app.
It will not sound better, and that is fine
A WAV made from an MP3 sounds exactly like the MP3: detail the MP3 left out cannot come back. What you gain is a file every editor opens directly, with nothing lost along the way.
Expect a much bigger file
WAV stores the sound uncompressed, so it takes about 10–12 MB per minute of stereo sound. A four-minute song that was 6 MB as an MP3 becomes about 42 MB.
Other files to WAV
The same tool turns M4A, FLAC and OGG files into WAV, and takes the sound from a video, too.

Why your audio never leaves your computer
Online converters upload your file to their servers, convert it there and send it back. That is slow for long recordings, so free plans cap the length or the number of files, and your recording sits on someone else's computer.
Here your own computer does the work, inside this tab. Nothing is uploaded, so there is nothing to cap: no length limit, no daily limit and no sign-up.
Questions
What kind of WAV do I get?
A standard 16-bit WAV with the same sample rate and channels as your file. It opens in every audio editor and player.
My phone system needs 8 kHz mono WAV. Can it do that?
Not yet. The WAV keeps the original sample rate and channels.
Can I convert several files at once?
Yes. Choose or drop several files together. They are converted one after another with the same settings, and you can download each one or all of them in one ZIP.
Is it really free?
Yes. Your computer does the work, so a file costs us nothing to convert. No account and no limits.
Is my file uploaded?
No. It is converted inside this browser tab and saved straight back to your computer.
Which browsers work?
Recent Chrome, Edge and Safari on a computer.
Can I use a video file?
Yes. Drop a video and you get its sound.
