Why convert MP4 to MP3?

Converting MP4 to MP3 is useful when:

• you want to listen to a conference or course without watching the video,
• you’re turning a recorded video into a podcast episode,
• you only need the music or soundtrack from a clip,
• you want to save storage by stripping away the video track.

MP3 files are:

• much smaller than videos,
• supported by all audio players,
• easy to send via email or messaging apps,
• perfect for offline listening on the go.

What bitrate should you use?

The bitrate controls both audio quality and file size:

• 128 kbps – good enough for voice content (talks, lectures, interviews).
• 192 kbps – solid balance for most use cases.
• 256–320 kbps – higher quality, ideal for music and important soundtracks.

Higher bitrate = better quality, but also a larger file.
