What is a .webm file?

WebM is an open, royalty-free, media file format designed for the web. It is primarily intended to offer a high-quality, open-source alternative for use in HTML5 video and audio elements. WebM files typically contain video streams compressed with the VP8 or VP9 video codecs and audio streams compressed with the Vorbis or Opus audio codecs. The container format is based on a profile of Matroska (MKV), which provides a flexible and extensible structure for storing multimedia data. WebM's open and royalty-free nature makes it an attractive option for web developers and content creators who want to avoid licensing fees and ensure broad compatibility across different browsers and platforms. It is widely supported by modern web browsers, including Chrome, Firefox, Opera, and Edge. The format is designed to be efficient for streaming and playback, making it suitable for online video distribution. WebM is also used in various other applications, such as video conferencing and screen recording.
