WebM vs MP4

Both WebM and MP4 are container formats used to store video, audio, and other multimedia content. The main difference lies in the different coding formats they support, and the resulting different scenarios to use.

WebM is advisable to use for online video sharing and streaming. The video coding formats WebM supports (VP8 and VP9) offer a higher compression ratio, making the WebM video smaller in file size at the same quality. Therefore, WebM normally requires a lower computational footprint to enable playback on any device and modern browser.

MP4, short for MPEG-4 Part 14, is the most commonly used container format. It was first released in 2001. After a decade of user accumulation, coupled with its good compatibility with various devices, MP4 is the leading commercial choice worldwide. Most representatively, the H.264 coding format supported by MP4, as of 2019, is used by 91% of video industry developers. So, if you want to get higher video quality and better compatibility, choose MP4.
