About this tool
Pull the soundtrack out of a video without any software: lectures, interviews, voice memos recorded as video, music from a clip you own. The converter decodes the audio track and saves it as a standard MP3 at the bitrate you choose. Any common video format works, not just MP4.
About the formats: MP4 is the universal video container, usually holding H.264 video and AAC audio. It plays on every phone, browser, TV, and editing program, which is why most platforms ask for it. MP3 is the universal lossy audio format. Practically every device, car stereo, and app made in the last 25 years plays it, and at 192-320 kbps it is indistinguishable from the original for most listeners.
