WebM converter
WebM is the format you reach for when video must live on the web on open terms: royalty-free codecs, native browser playback, no plugin politics. The conversion below encodes VP8 inside your browser with WebAssembly, so your clip stays on your machine while it happens.
What is WebM?
WebM is the web-native, royalty-free video format Google introduced in 2010, built on the VP8/VP9 video codecs and Vorbis or Opus audio. Every modern browser plays WebM directly, HTML5 video embraces it, and no patent licensing is attached to it anywhere in the chain. Outside browsers it is less at home: many desktop players, editing suites and devices still prefer MP4.
