Why convert to WAV
WAV is uncompressed, lossless, and supported everywhere — DAWs, video editors, mastering tools, and hardware all read it without fuss. Converting a compressed MP3 or M4A to WAV gives you a clean, editable file that won't lose more quality when you process it further. It's the safest format to hand off to another tool or collaborator.
Why WAV and not MP3 output
This converter outputs WAV, not MP3. Decoding to raw audio is built into your browser, but encoding MP3 needs a separate encoder library — and WAV is the better target for editing anyway, since re-encoding to MP3 would stack a second lossy compression on top of whatever the source already had. If you need MP3 at the very end, export it from your DAW after editing.
Nothing gets uploaded
The conversion happens entirely in your browser using the Web Audio API. Your file is never sent to a server, so even large or unreleased tracks stay completely private.
How to convert audio to WAV
One step: drop the file. Everything happens locally in your browser — your audio is never uploaded.
1. Drop your file
MP3, WAV, FLAC, or M4A. The file is decoded with the Web Audio API — nothing leaves your device.
2. It converts instantly
The audio is re-encoded to a clean 16-bit PCM WAV, faithful to the decoded source (no added dither or effects).
3. Download the WAV
Grab the WAV and load it into your DAW, video editor, or mastering tool — or head over to mastering and a lyric video.
What people convert to WAV for
A clean WAV is the right starting point for almost any audio work.
Editing & DAW import
Most DAWs and editors prefer uncompressed WAV — convert once and avoid quality loss as you keep processing.
Avoiding double compression
Editing an MP3 and re-exporting MP3 stacks lossy encodes. Converting to WAV first keeps every later step clean.
Compatibility
A tool or device that won't read your M4A or FLAC will almost always accept a plain WAV.
