Convert videos between different formats directly in your browser. All processing happens locally on your device - no uploads, completely private and secure.
100% Private: All video processing happens in your browser using WebAssembly. Nothing is uploaded to any server.
Powered by FFmpeg: Uses FFmpeg.wasm, a WebAssembly port of the popular FFmpeg multimedia framework.
Performance: Browser-based conversion is slower than native tools (typically 5-30x slower). This is normal due to WebAssembly limitations - be patient for longer videos!
Optimized Settings: Uses fast encoding presets optimized for browser performance. For best speed, use "Low" quality or smaller files.
First Load: The first time you convert, it will download ~30MB of libraries. Subsequent conversions are much faster.
Large Files: Very large videos (>500MB) may be slow or fail due to browser memory limitations.
