Make iPhone Videos Smaller, and Playable Everywhere
iPhones record video in HEVC (H.265), usually in HDRand often in 4K. Those files are big (around 6 MB for every second of 4K HDR video) and some Windows PCs, older Android phones and office software can't play them, or show HDR as grey, washed-out colours. This tool turns them into a standard MP4 (H.264) with normal colours, at the size you need.
On the iPhone Itself
- Open this page in Safari (iOS 16.4 or newer) and tap the upload area.
- Choose the video from Photos.
- Tap a size limit (for example 25 MB for email) or choose a quality, then tap Share on the result to send it straight to Mail or WhatsApp.
Keep Safari open on this page while it works; switching apps can pause it.
On a Windows PC or Android Phone
Copy the .MOV across (AirDrop, cable, Google Drive) and open this page in Chrome or Edge. If the computer can't decode HEVC itself, the tool uses a slower built-in decoder automatically; expect a few minutes for a long 4K clip.
Avoid Big Files Next Time
In Settings → Camera → Formats, "Most Compatible" records H.264 instead of HEVC (bigger files, but they play everywhere). Settings → Camera → Record Video lets you pick 1080p instead of 4K, which makes files roughly a third of the size.

Frequently Asked Questions
Why won’t my iPhone video play on Windows?
iPhones record in HEVC (H.265), which many Windows PCs can only play with an extra codec. Compressing it here turns it into a standard H.264 MP4 that plays everywhere.
Why does my iPhone video look washed out on other devices?
It was recorded in HDR. Players that don’t handle HDR show it grey and flat. This tool converts HDR to standard colours, so it looks right on every screen.
Does it work on the iPhone itself?
Yes, in Safari on iOS 16.4 or newer. Keep the page open while it works, then use Share to send the result.
