Why our MP4 → WAV converter?
Built for people who care where their files go.
Total privacy
Your MP4 file is decoded and re-encoded inside the browser tab. No server, no upload, no telemetry — even on huge files.
Blazing fast
No upload step means conversion starts immediately. Most files finish in less time than it would take to send them anywhere.
Free, no limits
No subscription, no daily quota, no "Pro" tier blocking large files. The free version is the full version.

Frequently asked
Is this MP4 → WAV converter safe for sensitive documents?
Yes. Conversion happens entirely inside the browser tab using WebAssembly and Web Workers. There's no server endpoint that could leak the file content.
Do I need to install anything?
No. Any modern browser (Chrome, Firefox, Safari, Edge) is enough — there are no plugins or downloads.
What's the file size limit?
There isn't one we impose. The practical limit is whatever your machine can fit in memory.
