Video Converter
Convert video to MP4 or WebM and shrink it to a target size — on your device via WebCodecs. Nothing is uploaded.
Your browser can’t run this tool.It needs the WebCodecs video encoder and decoder, available in the latest Chrome, Edge, Safari 16.4+, and Firefox 130+. Everything here runs on your device, so a supported browser is required — nothing is offloaded to a server.
