How to use it
Add an MP4 file, choose the MP3 bitrate and process. The browser first tries native audio reading and uses full local mode only when needed.
Recommended settings
128 kbps is enough for speech and quick sharing. Use 192-256 kbps for music or if the source audio is already clean.
Privacy
Your files are not uploaded to a server. The editor runs in your browser with local libraries from this site.
Limits
Large images can take longer on phones. If the browser slows down, process fewer files at once or choose a smaller output format.
