WebM
WebM is an open, royalty-free media file format designed for web use, primarily for video and audio content. It is based on the Matroska container format and uses the VP8 or VP9 video codecs and Vorbis or Opus audio codecs, optimized for efficient streaming and playback in web browsers. The format is widely supported by modern browsers and platforms, making it a standard choice for HTML5 video embedding.
Developers should learn WebM creation when building web applications that require video content, as it offers high compression efficiency and broad browser compatibility without licensing fees. It is particularly useful for streaming services, online video platforms, and interactive media where performance and accessibility are critical, such as in educational sites or e-commerce product demos.
