Where MOV files come from
MOV is what an iPhone writes when Settings has camera capture set to High Efficiency, and what every Apple camera app and QuickTime export produces. Anyone sharing footage from an iPhone with a Windows or Android user meets this format.
What changes when you convert MOV to MP4
| Container | QuickTime MOV rewritten as MP4, which is the same underlying structure with a different brand |
|---|---|
| Video | HEVC or ProRes re-encoded to H.264; existing H.264 is still re-encoded at CRF 23 |
| Audio | Re-encoded to AAC |
Worth knowing first
MOV and MP4 are close relatives, both built on the ISO base media format, so a MOV holding H.264 and AAC is often playable after nothing more than a rename. If your file will not open anywhere, the container is rarely the problem. It is the HEVC video inside, which is what this conversion actually fixes.
FAQ
Can I just rename the .mov to .mp4?
Sometimes. If the MOV holds H.264 video and AAC audio, the two containers are close enough that a rename often works. It fails when the file holds HEVC, ProRes or a timecode track, which is most modern iPhone and camera footage. Converting handles both cases without you having to check first.
Why is my iPhone video rejected by Windows apps?
Because of HEVC, not MOV. iPhones record HEVC by default to halve the file size, and Windows only decodes it with a paid codec extension from the Store. Re-encoding to H.264 removes the dependency, which is why the converted file simply opens.
Will I lose the recording date?
Creation time is carried across. Location data and the Apple-specific atoms are not, which is often desirable when sharing. Use the Metadata Cleaner if you want to be certain nothing identifying remains.
Is this MOV to MP4 converter really free and without upload?
Yes. The tool runs entirely in your browser using FFmpeg compiled to WebAssembly. Your MOV file never leaves your device — open the DevTools Network tab to verify zero uploads. No signup and no watermark. The practical size limit is the memory your browser gives this tab, which is generous on a computer and a few hundred megabytes on a phone.
