What is MP4?

MP4 is the world's most widely supported video container format. It efficiently stores video (H.264 or H.265), audio, and subtitles in a single file with excellent compression. MP4 is the standard for streaming platforms, social media, mobile devices, and video sharing — if you need one video format that works everywhere, MP4 is it.

Common uses for MP4

  • Video for YouTube, social media, and streaming services
  • Recording and sharing video on any mobile device
  • Web-embedded video that plays in all browsers
Note: MP4 with H.264 is widely supported but not fully open — H.264 is patent-encumbered, and H.265 has even more complex licensing.

Compatibility: Universal — supported by every browser, device, operating system, and video platform.
