How do you convert an MP3 to WAV?
-
Add your MP3s
Drag one or more MP3 files (or M4A, OGG, FLAC…) into the box.
-
Set up the WAV
WAV is already selected. Keep 16-bit for compatibility, or switch to 24-bit; change the sample rate if your software requires it.
-
Download
Start the conversion, listen to the result and download the WAV files one by one or as a ZIP.
WAV files ready for editing
16, 24 or 32-bit
16-bit for full compatibility (CDs, DJ decks, older software), 24-bit for the studio, 32-bit float for audio editing software.
Your choice of sample rate
Keep the MP3's rate or force 44.1 kHz (CD) or 48 kHz (video), mono or stereo, depending on what your software needs.
Several files at once
Convert a whole album or a set of sound effects and get them all together in a ZIP.
And the other way round
Need the reverse? Choose MP3 to turn your WAV files into small MP3s, or AIFF and FLAC for other lossless formats.
Why convert an MP3 to WAV?
WAV is the working format of audio: most editing software, samplers, DJ decks and distribution platforms accept it without question, whereas MP3 sometimes causes trouble (a few milliseconds of offset at the start of the file, refused playback, loading times). A WAV is also easier to cut and edit, with no extra loss each time you save. It's also the format required to burn an audio CD and by some radio stations and dubbing studios.
Does converting to WAV improve the quality?
No, and it's worth knowing: an MP3 lost part of its sound information when it was compressed, and converting it to WAV can't bring it back. The resulting WAV sounds exactly like the MP3, but it's about ten times larger (close to 10 MB per minute at 16-bit, 44.1 kHz, stereo). The benefit is compatibility and easier editing, not quality. If you have the choice, always start from the least compressed original file (FLAC, WAV, CD).
16-bit, 24-bit, 44.1 kHz or 48 kHz: which WAV should you choose?
16-bit at 44.1 kHz is CD quality and the most compatible setting: pick it if in doubt. 24-bit is the studio standard; it won't make an MP3 sound better, but some software or platforms require it. 32-bit float prevents any clipping while mixing in audio software. For the sample rate, keep the original unless told otherwise: 44.1 kHz for music and CDs, 48 kHz for a video edit, so your software doesn't have to resample.
And the reverse: WAV to MP3
To share a recording by email or in a messaging app, the reverse is more useful: choose MP3 in the formats and your WAV files become five to ten times smaller. For other conversions (OGG, Opus, M4R for iPhone, WMA…), use the Audio Converter; if you just need MP3, use Convert Audio to MP3.
Frequently Asked Questions
How do I convert an MP3 to WAV for free?
Drop your MP3 into the box: WAV is already selected. Start the conversion, then download the WAV file. It's free, with no sign-up and no limit on the number of files.
Will the WAV sound better than the MP3?
No. The WAV sounds exactly like the original MP3: the quality lost during MP3 compression doesn't come back. A WAV is simply more compatible and easier to edit.
Why is my WAV file so large?
WAV is uncompressed: about 10 MB per minute at 16-bit, 44.1 kHz, stereo, compared with 1 to 2 MB for an MP3. In mono, the size is halved.
Which bit depth should I choose: 16 or 24-bit?
16-bit if you're not sure: it's CD quality and accepted everywhere. Choose 24-bit only if your software or platform asks for it.
Can I convert a WAV to MP3?
Yes: choose MP3 in the output formats. The file becomes five to ten times smaller.
Are my files uploaded?
No. The conversion happens in your browser with FFmpeg: your files stay on your device.
