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.
Up to 5 audio files at a time are free, up to 10 free files a day in this browser. A Day Pass costs 3.99 pounds and removes both free limits for 24 hours.

How to use it
- Choose your audio files, or drag them onto the box.
- They are converted to WAV at the sample rate they were recorded at: 16-bit, or 24-bit when the original is a high-resolution lossless file such as a 24-bit FLAC.
- 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. Before your file is opened, this page locks itself: from then on your browser refuses to let it fetch, upload or send anything at all. You can check: once the page has loaded, switch off your internet connection and it will still work. How the lock works.
