Before you start
Drop in a .mp4 (or .m4v) file from a download, a phone camera, a screen recording or a video export.
192 kbps is the default and suits most video audio. Use 320 kbps for music and 128 kbps for speech-only footage where size matters.
Press Convert. FFmpeg reads the audio track, discards the video stream without decoding it, and hands you a downloadable MP3.
MP4 is the container of the modern web: phone recordings, YouTube downloads, screen captures, Zoom and Meet exports, camera footage and almost every video file that arrives by email or messaging app is an MP4 carrying H.264 video with AAC audio. That ubiquity is exactly why so many people end up hunting for an MP4 to MP3 converter — the video was the packaging, and the part they actually want is the sound inside it.
This tool copies nothing and re-encodes only what is needed. The video stream is dropped before it is ever decoded, so the pixels in your MP4 are never touched and the conversion takes seconds instead of minutes — a 700 MB video becomes a 10 MB MP3 without your CPU breaking a sweat. The audio is decoded from its original AAC and encoded to MP3 at the bitrate you choose. Subtitles, chapter markers and camera metadata are not carried over; if you need those, you want a subtitle tool rather than an audio converter.
Turning a lecture, conference talk or webinar recording into something you can listen to while driving or walking. Ripping the music track from a concert video for a personal playlist. Keeping just the spoken part of a screen recording instead of a file too heavy to send. Saving an interview for transcription. Trimming a camera clip down to its audio so it fits in a chat app. In each case the video is irrelevant, and an MP3 is roughly a twentieth of the size.
