MOV Compressor is a free online video compressor that shrinks iPhone, Mac and camera MOV files into small, widely playable H.264 MP4s. Everything runs inside your browser, so your video never leaves your device and there is no server size cap. Pick High, Medium or Low quality, or type a target size such as 20 MB for email, optionally drop the resolution to 1080p, 720p or 480p, and compress several files at once. No signup, no watermark and no daily limit.
