How to Convert a Video to MP4 on iPhone
Updated · 2 min read
A website wants MP4 and your iPhone recorded MOV. Or you downloaded an MKV or WebM that the Photos app won't even save. iOS has no “Save as MP4” button — not in Photos, not in Files. Here's the quickest way to get an MP4 out of almost any video, right on your phone, without uploading it anywhere.
Why convert to MP4?
MP4 is the format nearly everything accepts: Windows PCs, Android phones, smart TVs, web upload forms, video editors, and messaging apps. Other formats are common on the web and on computers, but iPhone apps often can't use them:
| Format | Where it usually comes from | Saves to the Photos app? |
|---|---|---|
| MOV | iPhone camera, screen recordings | Yes — but some PCs, Android apps and upload forms reject it |
| MKV | Downloads, PC recordings | No |
| WebM | Websites, browser screen recorders | No |
| AVI, WMV, FLV | Older cameras, Windows PCs | No |
| MP4 | Almost everywhere | Yes |
How to convert a video to MP4 on iPhone
- Get the app. Download Video & Image Converter — free to try, works offline, no account.
- Pick your video. Choose it from Photos or the Files app — downloads usually land in Files › Downloads. You can also tap Share in another app and send the video to the converter. Select several videos to convert them in one go.
- Choose MP4. Select MP4 as the output format. The recommended settings suit most videos; tap More settings if you want a specific codec, resolution or frame rate. The app shows the estimated file size before you convert.
- Convert and save. Tap Convert. Save the MP4 to Photos or Files, or share it right away.

H.264 plays on practically everything, including older Windows PCs, cheap Android phones and smart TVs. Choose it when you don't know what device the video is going to.
HEVC (H.265) gives a noticeably smaller file at the same quality. Every recent iPhone, iPad and Mac plays it, as do most modern TVs and phones. Choose it when the video stays in the Apple world or when size matters.
Can I convert to MP4 without uploading the video?
Yes — and on a phone it's the better way. Online converters make you upload the whole file over mobile data, usually cap file sizes on their free plans, and keep a copy of your video on someone else's server. Video & Image Converter does the work on your iPhone with hardware-accelerated encoding. Nothing leaves the device, and it works in airplane mode.
Can I convert several videos at once?
Yes. Select as many videos as you need and they're converted one after another with the same settings. You can switch to another app while it works — the conversion carries on in the background.
