MOV to MP4 converter
Turn iPhone MOV videos into MP4 files that play on Windows, Android, smart TVs and in every browser. No upload, no watermark.
Preset
Files never leave your device. Everything runs in this tab — nothing is uploaded.
…
Keep this tab open and the screen on — Safari on iPhone pauses background tabs.
This tab was in the background, so the browser may have paused the work. If it stalled, run it again with the tab open.

Get it on the App StoreClear Cleaner compresses all your large videos on the iPhone in one go and keeps their original date and albums.
How it works
- If the MOV already holds H.264 video, the page just repackages it into MP4 — seconds, with zero quality loss.
- If it’s HEVC (H.265), the iPhone default since iPhone 7, it’s re-encoded to H.264 so older Windows PCs, Android phones and TVs can play it.
- The file is read from disk in pieces by Mediabunny inside a Web Worker, re-encoded to H.264 and packed into an MP4 that plays on iPhone, Android, Windows and in browsers.
- Audio from an iPhone (AAC) is copied as is when possible, so voices don’t lose quality.
Good to know
- Keep the tab open and the screen on. iOS pauses background tabs, so compression stops if you switch apps.
- On iPhone, files above roughly 600 MB can make Safari run out of memory. Use a computer for long 4K clips — or the app, which works with the whole library.
- HEVC (H.265) — the iPhone default — decodes in Safari and in Chrome or Edge on most Macs and Windows PCs, but not in Firefox.
- One video at a time.
Questions
Are my files uploaded anywhere?
No. The file is read and converted by your browser in this tab. You can check it yourself: open the developer tools, switch to the Network tab and run a conversion — no request carries your file.
What’s the difference between MOV and MP4?
Both are containers built on the same standard. The real compatibility problem is usually the HEVC codec inside iPhone MOVs, not the container — which is why the page converts the video to H.264.
Will I lose quality?
With “Keep quality”, H.264 videos are copied bit for bit. HEVC videos are re-encoded at a generous bitrate; the file usually gets somewhat bigger, because H.264 is less efficient than HEVC.
How do I make my iPhone record MP4-compatible video?
Settings → Camera → Formats → Most Compatible records H.264. Videos will take noticeably more space, though.
Does it keep the sound?
Yes. iPhone audio (AAC) is copied into the MP4 unchanged.
