Convert MOV to MP4
100% private — runs on your device, never uploaded. Works offline once loaded.
MOV is what a QuickTime recording, a Final Cut export and most iPhone footage arrives as, and inside it is very often exactly the same H.264 video and AAC audio that an MP4 holds — only the wrapper differs. That is why this conversion is usually instant here: when the streams already suit MP4 they are copied across rather than re-encoded, so a two-gigabyte clip is rewrapped in seconds with no loss of quality at all. It matters because MOV is the format that gets refused — by Windows machines without QuickTime, by upload forms, by Android phones and by plenty of web players — while MP4 is refused by almost nothing. If the footage was recorded in HEVC on a newer iPhone, that too is carried straight across.
Frequently asked questions
Will converting MOV to MP4 lose quality?
Usually not a thing. When the video inside is already H.264 or HEVC it is copied into the MP4 untouched, so the result is bit-for-bit the same picture. Only footage in an unusual codec has to be re-encoded.
Why is it so fast?
Because nothing is decoded. MOV and MP4 are both containers around the same kinds of stream, so the work is rewriting the wrapper rather than rebuilding every frame.
Is my video uploaded?
No. The conversion runs in your browser, which is why there is no size limit and no queue.
