Why Convert WEBM to MP4?

Compatibility

WEBM is an open-source video file format that is widely used for online video streaming, particularly on YouTube and other web-based platforms. However, despite its popularity, WEBM has its limitations when it comes to compatibility and playback on various devices. This is where converting WEBM to MP4 comes in handy. MP4 is a more widely accepted and compatible file format that can be played on a broader range of devices, including smartphones, tablets, and smart TVs.

Performance

Although WEBM is a newer video compression technology and has better compression ratios than some MP4 type files such as MP4 AVC. This comes at a cost of CPU processing power and some CPUs will be unable to process the data fast enough. This is not the case for MP4 AVC as this video compression standard has been around for a very long time and does not require as much CPU processing power like WEBM.
