Some audio editors, DJ software, samplers, phone systems and voice tools only accept WAV. This turns an MP3 into a standard 16-bit WAV that opens everywhere. It all happens in your browser, so the file stays on your device.
Your file never leaves your device. Nothing is uploaded.

Drop an .mp3 up to 500MB. It's converted locally, never uploaded.
Conversion runs on FFmpeg, compiled to WebAssembly, inside this browser tab. Licences and source
No. WAV stores the MP3's sound exactly, without further loss, but it can't bring back what the MP3 compression removed. Expect a file about five to ten times bigger with the same sound.
Nowhere. The converter runs inside your browser tab, so the file is read and converted on your own device and saved straight back to it. It is never uploaded to Wave or anyone else, and we never see its name or contents.
Inputs up to 500MB. The WAV output is much larger than the MP3, so a very long MP3 (several hours) can run out of browser memory; convert shorter parts if that happens.
No. MP3 is ideal for transcription because it's small. Send the MP3 straight to the free Wave AI transcription tool; WAV only makes the upload slower.
