Common Questions

MP3 is an audio format, while MP4 can contain both video and audio. Converting MP3 to MP4 is useful when you need your audio in a video format for publishing, sharing or uploading to a service that works better with video.

People commonly convert songs, podcasts, interviews, voice recordings, lectures and other spoken audio from MP3 to MP4.

Convert it to MP4 and give it something to display. The audio stays exactly as it was; you're adding a video track alongside it so players and upload forms recognise the file as a video.
