What is inside a MOV file
MOV and MP4 are both containers: boxes for the picture and the sound. Inside an iPhone MOV the picture is usually HEVC (High Efficiency) or H.264 (Most Compatible). H.264 plays almost everywhere, HEVC does not.
Convert MOV to MP4
Convert MOV to MP4 so an iPhone or camera clip opens on any computer, phone or TV. Many files are ready in a second at exactly the same quality.

How it works
- Choose the MOV fileOff an iPhone, a camera card or a computer. The pickers already read From MOV, To MP4.
- See how it will convert“Instant, same quality” means the video is only repacked. Otherwise the picture is re-saved as H.264.
- Save the MP4IMG_0042.mov becomes IMG_0042.mp4. Open it on Windows, Android, a smart TV or in an upload form.
How the conversion works
MOV is Apple’s video format. iPhones, many cameras and Mac screen recordings save it. Apple devices play it, but Android phones, older TVs, some Windows apps and upload forms expect MP4. Converting gives you a file that simply works there.
Two ways it can go
- H.264 inside: the video moves into an MP4 box without re-saving. Instant, same quality, same size.
- HEVC inside: the picture is re-saved as H.264 so any device can play it. This takes a while, and the file can come out larger.
- The sound is kept as it is when MP4 allows it. Otherwise only the sound is re-saved, which is quick.
Why an iPhone video won’t play on Windows
Windows needs an extra HEVC codec for iPhone videos filmed in High Efficiency. Without it you get sound over a black screen. MP4 with H.264 is the one combination every device understands.
On iPhone, Mac or Windows
- iPhone or iPad: open the page in Safari and choose the clip from Photos or Files. Safari reads HEVC, so every iPhone video works.
- Mac: Safari, Chrome and Edge all work, with nothing to install.
- Windows: if the page says it can’t read the video, install “HEVC Video Extensions” from the Microsoft Store, or convert on a Mac or iPhone.
Tips
- Need a smaller file? Pick 1080p or 720p under “Picture size” in the gear.
- To avoid MOV trouble later, set the iPhone camera to Most Compatible in Settings → Camera → Formats.
What you get
- An MP4 with the same name, the same length and the same sound.
- Your MOV file, untouched.

Questions
Not when the video inside is H.264: it is only repacked. An HEVC video from an iPhone is re-saved and looks practically the same.
HEVC packs a picture into less data than H.264. When it becomes H.264 to play everywhere, the file can grow. Pick a smaller picture size or compress it afterwards.
They are close relatives that hold video and sound in a similar way. MP4 is the open standard every device supports. MOV is Apple’s own.
Open this page in Chrome or Edge, choose the MOV and press Save video. If the clip is HEVC and Windows can’t read it, the page asks you to install “HEVC Video Extensions” first.
Yes, in Safari or another browser. Choose the video from Photos or Files and save the MP4 back to the phone.
It becomes a standard-range H.264 MP4. Very bright parts can look a little flatter than on the iPhone.
Yes. The converter recognises the file, From switches to MKV or WebM, and you get an MP4 the same way. Their own pages explain what changes for those formats.
