Frequently asked questions
Which audio quality should I choose?
128 kbps is fine for voice and small files, 192 kbps is the sweet spot for music, and 320 kbps is near-CD quality for the best sound. Larger bitrates mean larger files.
Does my video leave my device?
Never. The audio extraction (a WebAssembly build of FFmpeg, loaded unmodified from a CDN) runs entirely on your device. Your file is processed locally and is never uploaded to any server.

Yes — 100% free with no signup and no watermark, and there are no limits on how many files you convert (files up to 500 MB are supported). Your MP3 downloads straight to your device, ready to use.
Which video formats can I upload?
