Convert MP4 to GIF, make GIFs from video, compress clips, and edit media locally with ffmpeg.wasm. No upload, no sign-up, no server queue.
🎬
Local video conversion
Video Convert runs FFmpeg directly in your browser with WebAssembly, so your media stays on your device.
Use it for MP4, WebM, MOV, MKV, GIF, audio extraction, thumbnails, and quick compression presets.
⚙️
What ffmpeg.wasm does
ffmpeg.wasm brings FFmpeg into the browser through WebAssembly, enabling video and audio processing without a backend conversion service.
It powers format conversion, compression, trimming, GIF creation, audio extraction, frame capture, and custom FFmpeg commands while keeping files local.
🔒
Private by default
Files are written only into the browser FFmpeg virtual filesystem while the conversion runs.
Large videos can take time because all work happens on your computer instead of a remote server.
