About the MP4 to MOV
Some Apple workflows, editing apps and clients ask for MOV, the QuickTime format. This converter rewraps MP4 videos as MOV in your browser. Since MP4 and MOV share the same structure and codecs, the H.264 or HEVC video and the AAC sound are normally copied as they are, so conversion takes seconds and loses no quality. Anything that can't be copied is re-encoded automatically. You can preview the MOV before downloading it.

MP4 and QuickTime
MP4 grew out of Apple's QuickTime format in the late 1990s, so the two share the same box-based structure. Converting between them rewrites the boxes, not the frames.
Workflows that prefer MOV
Final Cut Pro, Motion, some broadcast and agency workflows, and older Mac software sometimes expect MOV.
- Final Cut Pro and iMovie projects
- Client or agency delivery specs
- Older Mac apps
How it works without uploading
Your browser has a built-in video engine (WebCodecs) that phones and computers use to play and record video. This tool uses it through Mediabunny, an open-source media library, to read your file, change it and write a new one, all inside the page. Speed depends on your device: a recent phone or laptop handles a few minutes of HD video comfortably, while long 4K files take longer.
ProRes and other codecs
This tool keeps the codec that's already in the MP4. It doesn't create ProRes, which professional editors sometimes request; use editing software for that.
Checking the file in QuickTime
Open the downloaded MOV in QuickTime Player on a Mac and use Window > Show Movie Inspector to see the format, codec and size. The codec should match the original MP4, confirming that nothing was re-encoded.
Delivery specifications
If a client asks for MOV, check whether they also specify a codec such as ProRes 422, a frame rate or a resolution. This tool changes only the container; for other requirements use a video editor and export with their exact settings.
Going back to MP4
If you later need MP4 again, our MOV to MP4 converter reverses the process, again usually without re-encoding.
Phone and computer
The conversion is quick on any device, including iPhone and iPad in Safari. For the reverse trip use MOV to MP4, and for other video types try the Video Converter. For MKV files use MKV to MP4, and the Video Converter handles other types.

Frequently asked questions
Why convert MP4 to MOV?
Some Apple tools, broadcast workflows and clients specifically request MOV files. The picture is the same; only the container changes.
Does it lose quality?
Usually not. The video and sound are copied without re-encoding when they are H.264 or HEVC with AAC.
Will Windows play MOV?
Windows 10 and 11 play most MOV files in the Films & TV or Media Player apps, and VLC plays all of them.
Is MOV larger than MP4?
No. When streams are copied, the MOV is almost exactly the same size.
Which browsers work best?
Chrome and Edge on computers and Android support the most video formats. Safari 16.4+ and recent Firefox work too, but some codecs, such as HEVC in Firefox, may not be supported there.
Is my video uploaded?
No. It is processed on your own device with your browser's built-in video engine, so private videos never leave your phone or computer.
Does the MOV keep the frame rate?
Yes. Frame rate, resolution and timing are copied exactly.
Will Final Cut Pro import it?
Yes. Final Cut Pro and iMovie import MOV files with H.264 or HEVC video directly.
Can I convert many MP4s at once?
One at a time for now. Each conversion takes only seconds when the streams are copied.
