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.

Does WAV improve MP3 quality?

No. WAV is easier to edit, but it cannot restore detail already lost in MP3 compression.

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.
