MP3 to WAV converter

Turn an MP3 into an uncompressed WAV file for an editor, a DAW session, a mastering pass or a CD. The conversion runs in your browser: nothing is uploaded, and the file is ready in seconds.

This page needs JavaScript for the tool itself. Open it in a browser to use it.

How it works

Drop the MP3 on the page. Your browser decodes it to raw audio, this page resamples or mixes it if you asked for that, and writes a standard PCM WAV file that any audio program opens. The result is saved from your own device.

Bit depth and sample rate

16-bit at 44100 Hz is the CD standard and the safe default. Choose 24-bit when the WAV is going into a recording or mastering session, and match the sample rate to that session (44100 Hz for most music, 48000 Hz for video work). 32-bit float is for editors that work in floating point. Higher settings do not add quality to an MP3, they only avoid rounding when the file is processed again.

What a WAV cannot give back

MP3 removes detail to save space, and that detail is gone. Converting to WAV does not restore it. The point of the WAV is that the audio is now uncompressed, so an editor, a plugin chain or a mastering tool can work on it without adding a second round of MP3 loss.

Master the WAV for streaming

Mono or stereo

A stereo MP3 stays stereo unless you mix it down. Mono halves the file size and suits speech, podcasts and single-microphone recordings. A mono MP3 can be written as stereo when a program insists on two channels.

From the label's own toolbox

BeatRootRaga is an independent label. Reference tracks arrive as MP3 and sessions want WAV, so this converter is used in the label's own work and is online for anyone. When the MP3 is a song you want to practise or remix, the stem splitter separates it into vocals and instruments.

Questions people ask

Does converting MP3 to WAV improve the sound?

No. The WAV contains exactly what the MP3 contained, uncompressed. What it avoids is a second lossy step when the audio is edited, processed or mastered and saved again.

How big is the WAV?

About 10 MB per minute for 16-bit stereo at 44100 Hz, 15 MB per minute at 24-bit, double that at 96000 Hz. Mono halves it.

Which bit depth should I choose?

16-bit for CDs and general use, 24-bit for a recording or mastering session, 32-bit float only if your editor asks for it.

Is the MP3 to WAV converter free, and is my file uploaded?

Free, no account, and nothing is uploaded. The MP3 is decoded and the WAV written inside your browser.

Can I convert many files at once?

One file at a time on this page. Each conversion takes a few seconds for a typical song.
