How to convert MOV to MP4
Turn iPhone MOV videos into MP4s that play on every device and upload to any site.
Videos from an iPhone are saved as .MOV files, usually with HEVC video inside. That plays fine on Apple devices, but some Windows PCs, Android phones, TVs and upload forms don't accept it. MP4 with H.264 plays everywhere, and converting takes a minute.
How to convert MOV to MP4
- Open the video converter and choose your MOV file.
- Pick MP4.
- Keep the quality and size as they are, or make the file smaller on the way, for example 1080p instead of 4K.
- Press Save video. You get an MP4 that plays on any device and uploads anywhere.
The video is converted inside your browser, so even a big 4K file starts straight away, without an upload.
If the MOV won't open
To convert an HEVC video, your browser needs to be able to play it. Safari on a Mac and recent versions of Chrome and Edge on most newer computers can. If the video doesn't open, try another of those browsers, or do the conversion on a different computer.
Film in a more compatible format
On your iPhone, go to Settings › Camera › Formats and choose Most Compatible. New videos are then saved with H.264, which plays everywhere, though the files are bigger.

Questions
Does converting MOV to MP4 lose quality?
Very little if you keep the original size and quality. Choose a smaller size only if you also want a smaller file.
Why won’t my iPhone video play on Windows?
iPhone videos are often HEVC in a MOV file, which needs a paid extension on some Windows PCs. Converting to MP4 with H.264 fixes that.
Is there a file size limit?
No. Only your device’s memory limits it, and nothing is uploaded.
