How MP4 to MP3 conversion works

An MP4 file is a container that holds video and audio together. This tool uses FFmpeg, the free, open-source engine used by many professional video apps, to read only the audio track and save it as an MP3. It all happens inside your browser, so your video stays on your device and is never changed.
