MP3 to WAV
Drop an MP3 — we decode it and write out a 16-bit PCM WAV file ready for your DAW or audio editor. No upload.

How it works
Your browser already decodes audio. We pair that with a tiny encoder (pure JavaScript for WAV, or a slim WebAssembly codec for less common formats) and put it behind a drop target. The whole pipeline runs in your tab. The first conversion may take a moment to load the codec; after that it's instant and cached.
Why convert MP3 files
MP3 files are great for some workflows and frustrating for others. WAV fixes the common compatibility headaches without losing what matters about your audio.
FAQ

Can I convert multiple files?
Yes, drop several at once and you'll get a zip back.
How big can the file be?
Around 500 MB on a typical laptop. Past 1 GB the browser starts running out of memory.
