About the conversion
MOV is Apple's QuickTime container: it is what an iPhone camera records into and what Final Cut and iMovie export. On Apple hardware it causes no trouble at all, but outside it the trouble starts — Windows players, Android devices, TVs and some editing suites either refuse MOV or open it inconsistently.
The good news is that a MOV from a phone almost always holds plain H.264 — the very codec MP4 uses. When the codec inside already suits the target container, we only swap the container — the wrapper around the video track. That takes seconds even for large clips and, more importantly, leaves the picture untouched: quality stays exactly as it was. Re-encoding kicks in only when there is no way around it, and the tool tells you honestly which of the two paths was used.
The file is processed in your browser on your own device and is never uploaded — not to our server, not anywhere else. On the first run the browser downloads the engine once (~32 MB) and takes it from cache afterwards.
Frequently asked questions
Will converting MOV to MP4 lose quality?
Usually not. If the MOV holds H.264, we simply move the track into an MP4 container without re-compressing the picture, so the quality stays as it was. Re-encoding happens only when the contents are not accepted by MP4, and the tool shows which path it took.
Why is the conversion so fast?
Because in the typical case it is a container swap, not a re-compression. A full re-encode would take many times longer and would degrade the picture; changing the wrapper avoids both.
My iPhone video is HEVC — what then?
It will be re-encoded to H.264. Technically HEVC can sit inside an MP4 as-is, but such a file still would not open on an older TV or in an editing suite — so the actual problem would remain unsolved. We convert it to H.264, which everything understands.
Is my file uploaded to a server?
No. The conversion runs in your browser using your own device; the video is never transmitted.
What file size can I convert?
Aim for 500 MB. The limit exists because processing happens in the tab's memory — very large files may be too much for the browser, especially on a phone.
