WebM vs. MP4

Though WebM and MP4 share some similarities, they are quite different. Compared to WebM, MPEG-4 Part 14 (MP4) is a container format that follows ISO/IEC standards with one difference – it offers higher levels of compatibility. MP4 supports subtitles, audio, video, and images. It also supports multimedia components, such as user menus and interactivity.

The most obvious differences between the two include:

  • File size and quality – since WebM is an internet-optimized video format, it delivers a higher compression ratio and smaller files.
  • Royalties – both formats deliver exceptional streaming quality. However, MP4 is patented, whereas WebM is royalty-free.
  • Compatibility – compared to WebM, MP4 supports more web browsers and mobile and desktop devices. Most Apple devices, such as iPads and iPhones, don't support WebM playback.

Here's a comparison table on overall information on WebM vs. MP4.
