MP3 to WAV
Convert MP3 to uncompressed WAV, ready for editing, CD burning or any audio software.
About this tool
Editing software, mixing desks, audio CD burning and some phone systems want one thing only: WAV, the uncompressed reference format. Drop in your MP3s — up to ten at a time — and get back standard WAVs (16-bit PCM), accepted by every piece of audio software of the past thirty years.
A point of honesty that sets us apart from converters promising miracles: WAV does not restore the quality that MP3 compression removed. It only guarantees that no further loss will be added, and that your file will be accepted where an MP3 isn't. The conversion runs on your device, with no upload.
Frequently asked questions
Will the WAV sound better than my MP3?
No: MP3 compression has already discarded information, and no format can bring it back. The WAV reproduces exactly what the MP3 contains, in an uncompressed container — which is precisely what editing and burning software expects.
Why is the WAV ten times bigger?
Because it isn't compressed: every audio sample is written out as-is, roughly 10 MB per minute in stereo. That's the price of universal compatibility with professional audio tools.
What kind of WAV do I get, exactly?
16-bit PCM at the file's original sample rate — the standard accepted by editing software, CD burners and phone systems alike.
Can I convert a whole folder?
Up to ten files per batch: each one comes out as a WAV, and a "Download all" button gathers them into a ZIP.
Is it really free, with no sign-up?
Yes — the tool is free, needs no account and has no usage limit. Processing happens locally in your browser, so your data never leaves your device.
