WebAV

Why we included this project

Most video editing means either installing a desktop app or paying for server-side transcoding, but WebAV does the whole job in the browser using WebCodecs. It suits web products that need to join clips, stamp watermarks, burn in subtitles, add dubbing, or turn canvas animations into MP4 files, all inside Chrome, Edge, or Electron. Because processing happens on-device, user footage never gets uploaded, encoding costs disappear, and you can layer in custom Canvas and WebAudio effects. The SDK is roughly 20x faster than ffmpeg.wasm at encoding and weighs about 50KB gzipped, so it drops into an existing front-end without a native runtime.
