Browser-based video compression, without the upload step

ConvertMeow runs on ffmpeg.wasm, a video engine that runs inside your browser. Your video is processed entirely on this computer and never uploaded to any server. Short clips work best; for files over roughly 500MB, a desktop tool like HandBrake is usually more reliable.
