About MOV to MP4

Convert Apple QuickTime MOV files into MP4, the format that plays on virtually every device and platform. We re-encode to H.264 with ffmpeg.wasm at a quality you control, so your clip works everywhere from phones to web players.

The transcode happens entirely in your browser. Your MOV file stays on your device, keeping the conversion private.
