WebM VS MP4, Which is Better?

Some websites allow you to select between WebM and MP4 as different video file types with distinct properties. Which of these two video formats is best when you have to pick between them in some circumstances?

While both formats can produce high-quality video, MP4 does it far better. Moreover, WebM videos have a smaller file size than their MP4 counterparts, which is much preferable for anyone trying to download or share a video that is of a more manageable size.

Since MP4 is a universal format, it has higher compatibility and is preferred by most users. You should also be aware that WebM, unlike MP4, indicates a royalty-free video and is available to all. 

The ideal option for you will be an MP4 if you are concerned with video quality and support. However, WebM will be recommended if you want a small video size.
