How to convert MOV to MP4

  1. Drop your MOV video onto the box, or press Choose files.
  2. Press Convert. The first time, your browser downloads the converter engine, then the video is converted in a progress bar you can watch.
  3. Download your MP4 file when it finishes, or all of them as a ZIP.

MOV is Apple's QuickTime video format. iPhones record it, and it works well on Apple devices but less well elsewhere. MP4 is the video format that works almost everywhere: phones, TVs, browsers and social apps.

Common questions

Why convert MOV to MP4?

iPhones and Macs record in MOV. MP4 plays on Android, Windows, TVs and every social app, so converting a MOV is the usual way to share an iPhone video.

Will the video quality drop?

Slightly, because the video is encoded again. We use a high-quality setting, so most people cannot tell. Keep the original in case you want to convert again.

Is my video uploaded anywhere?

No. The conversion happens inside your browser tab, so your video never leaves your device. We cannot see it or keep a copy.

Why is it slow?

Video is heavy work, and it is done by your own device, not a server. A laptop or desktop is many times faster than a phone, and short clips are quick. Close other tabs to help.

Why was the first conversion slow to start?

The first time you convert audio or video, your browser downloads the conversion engine (ffmpeg, about 30 MB) from a public CDN. After that it is cached, so the next ones start straight away. Your files are not part of that download.

How big a file can I convert?

Everything runs in your browser's memory, so the limit is your device. We suggest about 500 MB on a computer and 100 MB on a phone. Beyond that, the tab may slow down or run out of memory. A computer is much faster than a phone.
