Why iPhone videos won’t play on Windows
Since 2017, iPhones record video in HEVC (also called H.265) by default and save it as a .MOV file. HEVC stores the same picture in about half the space of the older H.264 format, which is great for phone storage. But many Windows PCs can’t decode HEVC without an extra add-on, and some editing apps, older TVs and upload forms don’t support it at all.
Common symptoms:
- Sound plays but the picture is black.
- Windows says you need a codec or extension.
- An editor or website says the file isn’t supported.
- The video stutters or won’t open at all.
Fix 1: Convert the video to H.264 MP4 (works everywhere)
Converting to H.264 makes the video play on every PC, TV, phone and editor. It’s the best fix when you’re sending the video to other people, because you can’t control what they have installed.
- Open the HEVC to H.264 converter. Maximum compatibility is already ticked.
- Drop the video in. The details line shows “HEVC” if that’s the cause.
- Press Convert to MP4 and save the new file.
The conversion happens on your computer; your video isn’t uploaded.
Fix 2: Install HEVC support on Windows
Microsoft sells an inexpensive HEVC Video Extensions add-on in the Microsoft Store. Once installed, the Photos app, Films & TV and other built-in apps can play HEVC. Some PCs come with it already. This fixes playback on that one PC but not for anyone you share the video with.
Fix 3: Use a player that supports HEVC
Free media players such as VLC include their own HEVC support and play iPhone videos without any extension. Good for watching on your own computer; it doesn’t help editors or websites that reject the file.
Fix 4: Change your iPhone settings for the future
On your iPhone, go to Settings, Camera, Formats and choose Most Compatible. New videos will be recorded in H.264 and photos as JPG. Files are bigger, so this suits people who often move videos to Windows. Existing videos don’t change; convert those with Fix 1.
When you transfer photos and videos to a PC with a cable, the iPhone setting under Settings, Photos, Transfer to Mac or PC set to Automatic also converts files to compatible formats during the transfer.
Which fix should you use?
| Situation | Best fix |
|---|---|
| Sending the video to someone else | Fix 1: convert to H.264 |
| Editing in an app that rejects it | Fix 1: convert to H.264 |
| Uploading to a form that rejects it | Fix 1, or the compressor if there’s also a size limit |
| Just watching on your own PC | Fix 2 or Fix 3 |
| Stopping it happening again | Fix 4 |
What about MOV files that aren’t HEVC?
Older iPhones and Mac screen recordings save H.264 in a MOV file. Most Windows apps play these, but some websites only accept MP4. The MOV to MP4 converter repackages these in seconds without re-encoding, so quality is unchanged.
Still a black screen after converting?
Very occasionally the problem is the player, not the file. Try opening the converted MP4 in a different app, such as the Windows Films & TV app, a browser (drag the file into Chrome or Edge), or VLC. If none of them play it, re-convert from the original video rather than a copy that may have been damaged during transfer.

Why does my iPhone video play sound but no picture on Windows?
The video is HEVC, which that PC can’t decode. Convert it to H.264 or install HEVC support.
Is HEVC the same as H.265?
Yes, they’re two names for the same video codec.
Will converting to H.264 make the file bigger?
Usually, yes. H.264 needs more data than HEVC for the same quality.
How do I stop my iPhone recording HEVC?
Settings, Camera, Formats, then choose Most Compatible.
Can I convert iPhone videos for free?
Yes. FitVideo converts HEVC and MOV videos to MP4 for free, without uploading them.
