WebM is an open, high-quality video standard. It is commonly used for delivering online videos using the HTML5 tag. This format is supported by nearly all search engines, online video platforms, and some media player, for example, Google, Mozilla Firefox, Opera, YouTube, VLC.

However, by comparison, MOV is an MPEG4 video file format developed with Apple's proprietary compression algorithm. So most MOV files are running on Apple devices and applications.
