About MP3 to WAV conversion
WAV doesn’t restore what MP3 compression removed, but it stops further losses: you can edit, process and re-save a WAV as many times as you like. That is why editors and DJ tools often prefer WAV as a working format.
The converted WAV is about ten times larger than a 128 kbps MP3 (roughly 10 MB per stereo minute). Trim the part you need before converting to keep files manageable.
FAQ
Does MP3 to WAV improve quality?
No. The WAV is an exact copy of what the MP3 decodes to. It prevents further loss when you edit and save again.
What WAV format is created?
Standard 16-bit PCM WAV at 44.1 kHz, stereo or mono, readable by every audio program.
Are my files uploaded?
No. Audio is decoded, edited and encoded in your browser with the Web Audio API, WebCodecs and a JavaScript MP3 encoder. Nothing is sent to a server, so it also works on slow connections once the page has loaded.
Which formats can I open?
Anything your browser can decode: MP3, WAV, M4A/AAC, OGG Vorbis, Opus and FLAC, plus the audio track of MP4, MOV and WebM videos. Chrome and Edge support the widest range.
