Frequently asked questions
- What quality is the MP3?
- It's encoded as high-quality variable-bitrate MP3 (around 190 kbps), which is transparent for speech and music for most listeners.
- How long can the video be?
- Longer files take more time and memory because everything happens in your browser. Clips of a few minutes convert quickly; very long videos work best on a desktop computer.
- What if the video has no sound?
- There's nothing to extract — the conversion will fail. Check the video plays with sound first.
- Are my files uploaded to a server?
- No. Everything runs entirely in your browser — your files never leave your device.
