How to use MP3 to WAV

Add your MP3 files.

Choose stereo or mono.

Press Convert and download each WAV, or all as a ZIP.

WAV is uncompressed audio, the standard for editing in audio software and for maximum quality.

Audio is decoded by your browser, so formats your browser can play can be converted. Chrome and Edge support the widest range.

Are my files uploaded?

No. Everything happens in your browser on your own device. Your files are never sent to a server, so they stay private.

How long can the file be?

Up to about an hour of audio works on most computers. Very long files need a lot of memory because the whole track is decoded at once.

Which formats can I convert?

MP3, WAV, M4A/AAC, OGG/Opus, FLAC, and the sound from MP4, MOV and WebM videos.
