MP4 to MOV Converter (Free, Online, No Upload)

Convert any MP4 file to Apple MOV format right in your browser. Nothing gets uploaded to a server. MOV is Apple's preferred container for video editing, so this converter is handy when you need files ready for Final Cut Pro or other Apple tools. The conversion runs locally using FFmpeg compiled for your browser, so your files stay on your device from start to finish.
