FAQ

Is my file uploaded anywhere?

No. The conversion runs in your browser with WebAssembly, so the selected file stays on your device.

Why can conversion take a while?

Large videos need to be decoded and encoded locally. Keep the tab open while the browser finishes the export.

Does the tool add a watermark?

No. The exported file is watermark-free.

Can this extract microphone audio from a screen recording?

Yes, if the WebM contains an audio track, the tool can export that track as MP3.

Want professional polish?

The browser tools are great for quick format work. Aufzeichna's desktop app is built for polished screen recordings with smooth cursor motion, cinematic zoom, and export control.
