Many people are confused about WebM and MP4 formats. MP4 seems to be a worldwide popular video format for all scenarios. But sometimes WebM format is used because of its small size and quick loading.

Definition of WebM and MP4 Formats

1. What is WebM

WebM is a container format created by Google designed specifically for online streaming. This video file type usually comprises VP8, VP9, or AV1 video and Vorbis or Opus audio. The WebM format is now supported by practically all HTML5 web browsers, including Mozilla Firefox, Google Chrome, and Opera. You can upload WebM videos to YouTube, Skype, Vimeo, ooVoo, and other popular platforms directly. Unfortunately, however, this video format is not supported by Apple Safari or Internet Explorer without extra plugins, and many video players don't support it. You need to use third-party players to open and play WebM files.

2. What is MP4

MPEG-4 Part 14 (MP4) is a popular container format that can hold many videos, audio, subtitles, graphics, and chapters in a single file. Advanced content, such as 3D images, menus, and user interaction, is also possible. Moreover, it can be streamed over the internet in the same way that container formats like WebM or MKV can. Furthermore, MP4 is a universal file format because it can be utilized on a wide range of devices, including platforms, browsers, mobile phones, etc.
