Sometimes you want just the audio from a video — the soundtrack from a movie, a podcast recorded as a video, a lecture from YouTube, or a song from a music video. Converting MP4 to MP3 is one of the most common media tasks, and it is easier than ever before.

What is the Difference Between MP4 and MP3?

MP4 is a video container format. It holds both video frames and audio data bundled together. MP3 is an audio-only format — it extracts and compresses just the sound track from the video. Converting MP4 to MP3 strips out the video and gives you a small, lightweight audio file.

Why Convert MP4 to MP3?

  • Podcasts and lectures: Listen to video content on the go without wasting data on video.
  • Music: Play music videos as audio-only on your media player or phone.
  • Smaller file size: An MP3 is typically 10 times smaller than an MP4.
  • Compatibility: MP3 works on every device, including cars, old phones, and speakers.

What Audio Quality Will I Get?

The output MP3 quality depends on the original audio quality in your MP4. If the video has high-quality stereo audio, your MP3 will be excellent. If the video was recorded with a phone microphone, the audio quality will reflect that, regardless of the tool used.
