Why convert MOV to MP4?

MOV is Apple's QuickTime format used by iPhones and Macs; it often won't play or upload on Windows, Android and many websites. MP4 (H.264/AAC) is the universal video format that plays on every phone, computer, TV and website.

Are my files uploaded?

No. Processing happens in your browser using your device's built-in, hardware-accelerated video engine (WebCodecs), so your files never leave your device.

How long does it take?

Usually a fraction of the video's length on a modern computer or phone, because your device's video hardware does the work. Large 4K files take longer, and very large files are limited by your device's memory.

iPhones record MOV files using H.264 or HEVC. Because MP4 can hold the same codecs, the video is usually copied straight into an MP4 file in seconds with no quality loss — only the container changes. Portrait videos keep their orientation.
