About MOV to MP4 conversion

MOV is Apple's QuickTime format: it is what an iPhone records and what most Mac screen recorders save. MP4 is the format almost everything else expects, from Windows and Android to upload forms and editing apps. The useful fact is that MOV and MP4 are usually just two different boxes around the same video. Converting QuickTime to MP4 here repackages that video into an MP4 box without re-encoding it, which is why it is quick and why the quality does not change.

How to convert MOV to MP4

What people use it for

Good to know: recent iPhones record in HEVC by default, and repackaging keeps HEVC inside the MP4. It plays on current phones, Macs and up-to-date Windows, but some older players do not support HEVC. That is a codec limit, not a conversion error.

Frequently Asked Questions

How do I convert MOV to MP4?
Drop your MOV file onto the page and click Convert to MP4. Most MOV files are repackaged into MP4 without re-encoding, so it takes seconds rather than minutes. Preview the MP4, then download it. Everything runs in your browser, and your video never leaves your device.
Does converting MOV to MP4 lose quality?
Usually not at all. MOV and MP4 are containers that normally hold the same video, so the video stream is copied into MP4 unchanged and quality is identical. If a file cannot be repackaged, it is re-encoded to H.264 instead, which takes longer and is very close to the original.
Will the MP4 play on Windows and Android?
Almost always. One caveat: recent iPhones record in HEVC by default, and repackaging keeps HEVC inside the MP4. Current phones, Macs and up-to-date Windows play HEVC, but some older players and apps do not. If yours will not open it, that is the reason.
Is my video uploaded to a server?
No. The conversion runs on your own device using FFmpeg compiled to WebAssembly, so your video never leaves your device.
Is there a file size limit?
No fixed cap. The practical limit is your device memory. Repackaging is light, so even long clips usually convert quickly.
