Convert MP4 to MOV
100% private — runs on your device, never uploaded. Works offline once loaded.
MOV is QuickTime's container and the one Apple software prefers — Final Cut Pro, iMovie and QuickTime Player itself are all happier with it, and some older Apple workflows will not import an MP4 at all. The useful fact is that both containers usually hold identical H.264 and AAC streams, so this conversion is normally a rewrap: the streams are copied into a MOV wrapper without being decoded, which takes seconds and changes not a single pixel. That makes it the cheapest fix there is for a file an Apple editor is refusing, and unlike a re-encode it can be undone just as cleanly by converting back.
Frequently asked questions
Is MOV better quality than MP4?
No — they are containers, not codecs. The same video in either wrapper is the same quality; MOV is simply what some Apple software expects.
Why was it instant?
Because the H.264 video and AAC audio inside your MP4 are already valid in a MOV, so they were copied rather than re-encoded.
Is anything uploaded?
No. The rewrap happens in your browser.
