What is a MP3 para WAV?
WAV is the uncompressed format most audio editing software and DAWs expect as input — editing or processing an MP3 directly can add extra generation loss on top of what MP3's compression already discarded, so converting to WAV first gives a clean, unencoded starting point.
How to use the MP3 para WAV
- Add an MP3 file
- It's decoded and re-encoded to WAV, on your device
- Download the WAV file
Example
A 4-minute MP3 at 3-4MB converts to a WAV file around 40MB — WAV stores every sample uncompressed, so a roughly 10x size increase is expected, not a sign anything went wrong.

Frequently asked questions
Is my audio file uploaded anywhere?
No — MP3 para WAV runs entirely in your browser using JavaScript/WebAssembly. Your audio file is never sent to a server.
Is there a file size limit?
Free use covers files up to 100MB per file; signing up for Pro raises that to 500MB.
Why does this need a modern browser?
This tool runs a real audio engine (FFmpeg, compiled to WebAssembly) inside the page, which needs a browser feature called SharedArrayBuffer to work. Every current version of Chrome, Firefox, Edge, and Safari supports it — if you see a compatibility warning, try updating your browser.
