ffmpeg.wasm is a pure WebAssembly (and JavaScript/TypeScript) port of FFmpeg that enables in-browser media recording, conversion, and streaming—letting developers perform video/audio processing entirely client-side without server uploads. Transpiled via Emscripten from FFmpeg and its codecs into WebAssembly. Supports both single-threaded and multi-threaded cores using web workers. Written in TypeScript for improved developer experience.
