Frequently Asked Questions

MP4 (MPEG-4 Part 14) is the most common “lossy” file format for digital videos. It acts as a “container” format because it bundles different types of data, including video, audio, and subtitles, into a single file. As a standard format for current streaming platforms, MP4 creates high-quality video with relatively small file sizes.

MP3 is the global standard for digital audio files. It’s a compression format designed specifically to hold sound. By removing sound data hard for the human ear to hear, MP3 makes the file size very small while still keeping good sound quality. It’s known as the most compatible audio format in the world. Almost every car stereo, phone, computer, and music player can play MP3 without hassle.

The biggest difference is what they can hold. MP4 is for video, while MP3 is for audio.

  • MP4: holds moving pictures, sound, and subtitles. It is what you use to watch a movie or a clip.
  • MP3: Stores only sound. It is what you use to listen to music or to set as a ringtone.
