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.

Why convert M4A to MP3?

MP3 is accepted by more apps, upload forms, and older playback devices.

Want professional polish?
