How to Convert MOV to MP4 on iPhone

Quick answer
To convert MOV to MP4 on iPhone, install the free ConvertEase app, tap Video, select your MOV clip, choose MP4 as the output, pick a quality, and tap Convert. The MP4 is processed on your iPhone and saved to your library — free, offline, and with no watermark.
Your iPhone shoots gorgeous video — but it saves it as MOV, and that's where the trouble starts. Send a MOV to a Windows laptop, an Android phone or a website upload box, and it might not play. The universal fix is MP4, the format virtually every device and platform supports. Here's how to convert it right on your iPhone.
MOV vs. MP4: what's the difference?
MOV is Apple's QuickTime container; MP4 is the cross-platform standard. They often hold the same kind of video inside, but MP4 enjoys far wider support — YouTube, Instagram, Windows Media Player, Google Drive previews, video editors and most upload forms all prefer it. Converting MOV to MP4 simply rewraps (and optionally re-encodes) your clip so it plays everywhere.
How to convert MOV to MP4 on iPhone (step by step)
- Download ConvertEase free from the App Store and open it.
- Tap Video and select the MOV clip from your library.
- Choose MP4 as the output and pick a resolution & quality.
- Tap Convert — the MP4 is processed on-device and saved to Photos.
ConvertEase also handles MKV, AVI, WEBM, M4V and more — see the full iPhone video converter.
Why convert on-device instead of an online converter?
| Factor | ConvertEase (on-device) | Online MOV-to-MP4 site |
|---|---|---|
| Upload time | None — instant | Must upload the whole video |
| File size limit | No cap | Often limited to short clips |
| Privacy | Video never leaves your iPhone | Uploaded to a stranger's server |
| Watermark | None | Common on free tiers |
Videos are big files. Uploading a 2-minute 4K clip to a website can take longer than the whole conversion does on-device — and you'd be handing your footage to a server you don't control.
Tip: shrink the file at the same time
If your MP4 still needs to be smaller (for a text message or upload cap), lower the resolution or bitrate during conversion, or compress it afterward. See how to compress video on iPhone.
