About This Tool
Why use MP3 to WAV?
Decode an MP3 into an uncompressed WAV file. FFmpeg runs in your browser and writes out raw PCM audio, which is what editing software, DAWs, broadcast systems and some hardware samplers want to work with.
Be clear about what this does and does not do. WAV is lossless, but decoding an MP3 does not restore anything the MP3 encoder threw away — that detail is gone permanently. What you get is an exact, uncompressed copy of the audio as it currently exists, which is the right starting point for editing because every subsequent save will not compress it again. Expect the file to be roughly ten times larger: uncompressed CD-quality stereo runs at about 10 MB per minute.
Key Benefits
Uncompressed PCM
The format editing software and DAWs expect, so no decoding happens on every playback and no further compression is applied.
No further loss
Once in WAV, editing and saving repeatedly will not degrade the audio the way re-saving an MP3 does.
Runs in your browser
FFmpeg executes in the tab, so recordings are not uploaded to a conversion service.

MP3 to WAV FAQs
Does converting to WAV improve the quality?
No. MP3 encoding discards audio permanently and decoding cannot bring it back. WAV stops any further loss from this point, which is a different and still useful thing.
How much bigger will the file be?
Roughly ten times. Uncompressed stereo audio at CD quality is about 10 MB per minute, against roughly 1 MB per minute for a 128 kbps MP3.
Why would I want WAV at all?
Editing software works natively with uncompressed audio, hardware samplers often require it, and broadcast specifications usually mandate it. It is a working format, not a listening one.
Is my audio uploaded?
No. The conversion runs in your browser, so recordings and unreleased tracks stay on your device.
