MP3 to WAV
Some editing software, sound equipment and phone systems need WAV files. Convert MP3 and other audio to WAV here, entirely on your own device.
Your files never leave your device
How to use it
- Choose your audio files, or drag them onto the box.
- They are converted to 16-bit WAV at 44.1 kHz, the same standard as a CD.
- Download each WAV, or all of them as a ZIP file.
Expect much larger files
WAV does not compress sound, so it takes about 10 MB for every minute. Converting an MP3 to WAV cannot restore detail the MP3 left out; it makes the sound easier for other software to handle, not better.
Questions
Are my files uploaded?
No. The work happens inside your web browser, on your own device. You can check: once this page has loaded, switch off your internet connection and it will still work. The page also tells your browser to refuse to load anything from, or send anything to, any other website, so nothing can be sent elsewhere even by accident.
