Why Extract MP3 from MP4
Sometimes you only need the audio from a video—music tracks, podcasts, lectures, or interviews. Extracting MP3 from MP4 removes the video, creating a compact audio-only file.
MP3 files are much smaller than video files, saving storage space and making them perfect for audio players, phones, and sharing. You can listen to content without watching the video.
