This MP3 to WAV converter produces an uncompressed WAV from any MP3 — the format audio editors, samplers and processing tools want as input. Drop the MP3, download the WAV, all in your browser.
There are no quality settings because the conversion is lossless: the WAV stores exactly the audio the MP3 decodes to, sample for sample.

When a WAV Copy of an MP3 Is Exactly Right
Converting MP3 to WAV does not add quality — the compression baked into the MP3 is already there. What it does is hand your audio to tools that want uncompressed input. Audio editors cut and process more predictably on WAV; samplers and effect units expect it; some speech-analysis and transcription workflows require it; and joining or splicing several files is cleaner when they share an uncompressed format. WAV is also the safe intermediate when you plan another conversion step — converting WAV to something else avoids stacking lossy generations.
Size expectations, stated plainly: the WAV will be about ten times larger than the MP3 — CD-quality audio runs around 10 MB per minute uncompressed. That is not a defect; it is the format doing its job. The WAV is a working copy, not a sharing copy — keep the MP3 for sending around and the WAV for processing.
What the conversion actually does: the browser decodes the MP3 to raw samples and writes them, with the original sample rate and channel count, into a standard WAV file. One decode, one write, no quality trade-offs to tune — which is why there are no options here.
As everywhere on this site, the job runs in your browser. The MP3 is decoded and saved locally, nothing is uploaded, and there is no account, watermark or limit.
Frequently Asked Questions
No — it sounds exactly the same. The WAV preserves what the MP3 decodes to, without adding loss, but it cannot restore what MP3 compression removed.
WAV stores raw samples uncompressed — about 10 MB per minute. That is the nature of the format, and exactly why editors want it.
The MP3's own sample rate (usually 44.1 kHz), unchanged. If a platform needs a different rate, use the Resample Audio tool afterwards.
Yes — that is the main use case. Import the WAV into your editor, process freely, and export your final format at the end.
One at a time here, but with no usage limit — run them through one after another.
No — the decode and save run in your browser.
