You can convert MP3 to WAV for free above: just know the WAV will sound identical to the MP3, not better; lossless can't restore discarded detail.

Let's be straight with each other: converting MP3 to WAV will not bring back detail the MP3 encoder already threw away. What you do get is a WAV that behaves like one: built for recording, editing and mastering, where every last bit matters: which is often exactly what an editor, burner or archive pipeline demands instead of an MP3.

FYI

Honest warning: a WAV made from MP3 is lossless from here on, but it can't restore what the MP3 encoder already discarded. It will sound exactly like your MP3: just bigger.

Why flip MP3 to WAV

MP3 is the format that taught music to travel: small, scrappy, and welcome absolutely everywhere. It was born in 1993, Fraunhofer Institute, Germany, and its real weak spot is holding fine detail at low bitrates: it stays small by quietly discarding sound.

WAV is audio with nothing taken away: every sample intact, every megabyte accounted for. Raw PCM samples in a RIFF wrapper. No compression of any kind. That makes it the right destination when what you need is recording, editing and mastering, where every last bit matters.

Questions people ask

Will converting MP3 to WAV lose quality?

It won't lose more, and it won't gain any back. The WAV preserves your MP3 exactly as it is now: including whatever the original lossy encode discarded.

Will the WAV file be bigger or smaller than my MP3?

Bigger: usually several times bigger. WAV runs about 10 MB per minute at CD quality: ten times the size of an MP3, and none of that extra space adds quality to an MP3 source.

Where will the WAV file play?

Universal on desktops and pro audio gear; clumsy on the mobile web. That's the usual reason people leave MP3 behind: WAV simply opens in more of the places that matter.

How long does MP3 to WAV conversion take?

Seconds for most files: audio is light work. A long recording might take a minute; your file auto-deletes from our servers within an hour either way.
