What is a WAV en 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 en 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 en 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.
