Practical video guide
Make an iPhone video easier to use on Windows
Convert an iPhone MOV to MP4 when a Windows app or website will not accept it.
The short answer
If an iPhone video will not open, import, or upload on Windows, create an MP4 copy and try that instead.
Clip Squeezer creates a new file and leaves your original untouched.
Why this happens
An iPhone may save video in a form that newer Apple devices understand but a particular Windows app does not. The .MOV ending is only part of the story; the way the picture is stored inside also matters.
What should I choose?
Convert to MP4
Use this when the MOV will not open or import.
Works almost everywhere
Use Make smaller with this option if the problem is HEVC support as well as file size.
No conversion
If the original opens and uploads correctly, keep using it. A new file is unnecessary.
Do it with Clip Squeezer
- 1
Copy the original video to the Windows computer.
- 2
Add it to Clip Squeezer and choose Convert.
- 3
Choose MP4. Clip Squeezer checks whether it can copy the picture as it is or needs to make a more compatible version.
- 4
Test the new MP4 in the exact editor, player, or upload form you need.
Check the new file
Test the MP4 in the actual Windows program you need. Check portrait videos for correct rotation and make sure the sound remains in time near the end.
Common questions
Why does one MOV work while another does not?
MOV files can contain different kinds of picture and sound. The filename ending alone does not tell Windows everything it needs to know.
Will this reduce iPhone video size?
Conversion alone may not. Choose Make smaller when size is the problem.
