Why won't my iPhone video play on Windows?

If a video copied from your iPhone won't open on Windows, shows a black screen or only plays sound, you're not alone. The video isn't broken, it's the format the iPhone uses.
iPhone video to MP4Fix iPhone videos that won't open on Windows.The cause: HEVC (H.265)
To save space, iPhones record video in HEVC, also called H.265, by default. It produces files almost half the size at the same quality.
The catch: Windows can't play HEVC out of the box. It needs a separate extension from the Microsoft Store that most PCs don't have. Some older Android phones, smart TVs and video editors have the same problem.
The easiest fix: convert it to MP4 (H.264)
Converting the video to H.264 MP4, which plays everywhere, solves the problem completely. mp4indir.com does it in your browser without uploading the video.
- 1Open the iPhone video to MP4 tool.
- 2Drag and drop the video or pick it from your computer.
- 3Choose a quality and press Start. Download the MP4 when it's done.
The iPhone setting that prevents it
If you want new videos to play everywhere, go to Settings, Camera, Formats on your iPhone and choose Most Compatible instead of High Efficiency. Videos will be recorded in H.264 from then on. The only downside is that they take a bit more space.
If the video is still too big
iPhone videos are recorded at high resolution, so they can be large even after converting. Shrink them before sharing with the compress video or change resolution tools.
