What Are MP3 and MP4?

MP3 and MP4 are ways to save and play music and videos on phones, computers, and other devices.

MP3 is for audio. When you listen to music on your phone, it might be in MP3 format. It makes music files smaller so they do not take up too much space.

MP4 is for video. It saves both audio and visuals. Movies, cartoons, and YouTube videos are often MP4 files.

Both MP3 and MP4 help people enjoy music and videos anywhere. They make it easy to listen to, watch, and share recordings.

Next time you play a song or video, you might be using MP3 or MP4!
