What is a WAV a MP3?
A raw WAV recording from a mic, DAW export, or voice memo app is often 10x larger than it needs to be for sharing — MP3's lossy compression shrinks that dramatically while staying perceptually close to the original, which is why it's the default for podcasts, music sharing, and email attachments.
How to use the WAV a MP3
- Add a WAV file
- It's encoded to MP3 at 192kbps, on your device
- Download the smaller MP3 file
Example
A 40MB WAV voice recording converts to a roughly 4MB MP3 at 192kbps — small enough to email directly, with quality that's indistinguishable from the original for spoken word at normal listening volume.

Frequently asked questions
Is my audio file uploaded anywhere?
No — WAV a MP3 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.
