MP4 to MOV converter
MP4 and MOV are the same underlying format, so an H.264/AAC video moves across into a MOV untouched — no re-encoding, no quality loss. It all happens in your browser and the file never touches a server.

MOV is Apple's QuickTime container, and it's the format Final Cut Pro, iMovie, and Apple Motion reach for by default — so a video exported as MP4 sometimes needs a .mov extension before those apps treat it as a first-class import. Because MP4 (MPEG-4 Part 14) was standardized directly from QuickTime's file format back in the early 2000s, the two are structurally almost identical, which is exactly why swapping the wrapper takes no re-encoding. If you've run into "Final Cut won't import my MP4" or just want a file that opens in QuickTime Player with a double-click, this is the quick fix.
One thing worth knowing: renaming a file from .mp4 to .mov in Finder is not the same as remuxing it — the container header has to be rewritten so players read the streams correctly, and that's what this tool does properly. For Suno creators the usual path is exporting a lyric video or visualizer as MP4, then rewrapping to MOV to drop it onto a Mac editing timeline. Hang on to the original MP4 too, since it stays the more portable choice for uploading to YouTube, Instagram, or sharing with anyone outside the Apple ecosystem.

When to use it
- Importing a Suno visualizer or lyric video into Final Cut Pro, iMovie, or Apple Motion, which list and expect .mov files in their import dialogs.
- Sending a clip to a Mac-based collaborator or client who wants to double-click it open in QuickTime Player instead of a browser or VLC.
- Loading footage into software that only offers .mov in its file picker, such as some Keynote video embeds or older VJ and motion-graphics apps.

FAQ
Is the video re-encoded?
No — MP4 and MOV share the same ISO base media container, so the existing H.264 and AAC streams are copied straight across. It's lossless and near-instant.
Will every MP4 convert cleanly?
Remux only re-wraps the streams, it doesn't change the codec. Standard H.264/AAC files open fine as MOV; an unusual codec that QuickTime or Final Cut can't read won't play just because the extension changed.
What actually differs between an MP4 and a MOV file?
Both use Apple's QuickTime-derived ISO base media format, so for everyday H.264/AAC video they're interchangeable. MOV is the older, Apple-native container and can additionally hold things a standard MP4 can't — ProRes video, an alpha transparency channel, and timecode tracks — which is why pro Apple apps favor it.
Does the MOV end up larger than the MP4?
No. Remuxing copies the same audio and video data across and only rewrites the container header, so the MOV lands within a few kilobytes of the original. File size is driven by the encoded streams, not the extension.
Will Final Cut Pro edit the MOV more smoothly than the MP4?
Not on its own. The extension changes but the codec doesn't, and H.264 is a long-GOP format that stays heavy to scrub and trim. Genuinely smooth editing comes from transcoding to ProRes, which is a full re-encode this lossless remux deliberately doesn't do.
