MP4 is a video format, so it carries both picture and sound. When you only need the sound — a song, a talk, a recorded call — converting the MP4 to MP3 gives you a small audio file that plays on any device or music app.
This tool extracts the audio track from your MP4 and encodes it as an MP3 without uploading anything. The work is done locally in your browser, so even private recordings stay on your device.
