When you need WAV from an MP3
WAV is the format nearly every audio program can open without a codec. Editing software works on WAV without decoding as it goes, DJ software and samplers load it instantly, audio CDs are burned from it, and many phone systems and hold-music players accept nothing else.
- Video and audio editors that stutter on MP3 timelines
- DJ software and samplers
- Burning an audio CD
- Phone systems, IVR and hold music
- Uploading to a service that asks for WAV
Will it sound better?
No — and nothing is lost either. Converting MP3 to WAV writes out exactly what the MP3 decodes to. What MP3 compression removed when the file was made stays removed; the WAV is simply easier for other software to handle, at about ten times the size.
Step by step

Frequently asked questions
How do I convert MP3 to WAV for free?
Drop the MP3s onto this page and click Convert to WAV. It runs in your browser with no upload, no account and no limit on the number of files.
Does converting MP3 to WAV improve quality?
No. The WAV contains exactly what the MP3 decodes to — no better, no worse. It is useful when software needs WAV, not for improving sound.
What WAV settings does it use?
16-bit PCM at the MP3’s own sample rate (usually 44.1 or 48 kHz), mono or stereo as the MP3 was — the settings every program accepts.
How big will the WAV files be?
About 10 MB per minute for stereo at 44.1 kHz. A four-minute song becomes roughly 40 MB.
Are my files uploaded?
No. The conversion happens entirely in your browser; your MP3s never leave your device.
