About MKV to GIF

Turn a short MKV (Matroska) video into a looping animated GIF. Set the frame rate and width and we render an optimized GIF — perfect for reactions and demos.

The conversion runs entirely in your browser via WebAssembly — FFmpeg compiled to WASM — so your MKV clip is never uploaded to any server.
