Quality settings
"High" encodes the MP3 at the best variable bitrate (around 190–250 kbps), which is indistinguishable from the original for almost everyone. "Standard" makes files about a third smaller and is fine for speech, lectures and podcasts.

Frequently asked questions
- Are my files uploaded?
- No. Processing happens in your browser using your device's built-in, hardware-accelerated video engine (WebCodecs), so your files never leave your device.
- How long does it take?
- Usually a fraction of the video's length on a modern computer or phone, because your device's video hardware does the work. Large 4K files take longer, and very large files are limited by your device's memory.
