About the conversion
The reverse task shows up for people editing on a Mac: Final Cut Pro, iMovie and some plugins prefer the QuickTime container over MP4, even though the track inside can be the very same H.264.
That is exactly why the conversion is usually close to instant. 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
What is the difference between MOV and MP4?
They are different containers for the same tracks. Apple built MOV for QuickTime, and MP4 is the international standard derived from it. Both usually hold H.264 video with AAC audio, so moving between them rarely needs re-compression.
Why use MOV at all when MP4 exists?
For Apple's editing software and certain plugins that expect the QuickTime container. For viewing and sharing, MP4 is the more universal choice; MOV makes sense when the file goes into a Mac workflow.
Will the quality get worse?
No, provided the codec inside fits: we change the container without touching the picture. After the conversion the tool shows whether the track was moved or fully re-encoded.
Is the audio preserved?
Yes, the audio track moves along with the video. If its codec does not suit the container, it is re-encoded to AAC with no noticeable loss.
Does the video go to a server?
No, everything is computed locally in the browser — the file never leaves your device.
