MP4 to WEBM

MP4 is a digital multimedia container format most commonly used to store video and audio, but it can also be used to store other data such as subtitles and still images. It allows streaming over the internet and is universally supported across hardware players and modern browsers.

WebM is an open, royalty-free media file format designed for the web. Originally sponsored by Google, it provides highly efficient video compression suitable for HTML5 video playback, offering high quality at smaller sizes.
