WebM is an open, royalty-free multimedia file format designed for web video streaming and HTML5 video playback. Developed by Google, it uses the VP8/VP9 video codecs and Vorbis/Opus audio codecs, offering high-compression web-optimized video with excellent quality. WebM files typically have .webm extensions and are widely supported by modern web browsers for efficient, lightweight video delivery.
High compression efficiency, royalty-free format, excellent web compatibility, open-source standard, supports adaptive streaming, smaller file sizes, superior quality at lower bitrates, and native support in modern browsers like Chrome, Firefox, and Edge.
Limited support in older browsers, less universal than MP4, potential quality variations between different VP8/VP9 encoders, and reduced compatibility with some professional video editing software and media players.
WebM is primarily used for web video streaming, online video platforms, HTML5 video embedding, and digital media distribution. Common applications include YouTube video streaming, web-based video conferencing, online learning platforms, responsive web design, and open-source multimedia projects that require efficient, patent-free video compression.
