About MOV to MP4

MOV is Apple's QuickTime container, used by iPhones, Macs and many cameras. This tool converts a MOV into an MP4 with H.264 video and AAC audio, which is easier to play and upload on Windows, Android and web platforms that are picky about QuickTime files.

When it helps

  • Sharing an iPhone video with someone on Windows or Android whose player will not open the MOV.
  • Uploading a clip to a website or form that only accepts MP4.
  • Converting iPhone footage recorded in HEVC (H.265) to H.264 for older devices and editing software.
  • Turning a QuickTime screen recording from a Mac into a smaller MP4 for a bug report.

Tips

  • Recent iPhones record in HEVC by default. Re-encoding to H.264 makes the file play almost everywhere, but at the same quality an H.264 file is usually larger than the HEVC original.
  • Raise the CRF slider (towards 30 or more) if you mainly want a smaller file for messaging; lower it (around 20) if you plan to edit the result.
  • iPhone HDR (Dolby Vision) clips are converted to standard 8-bit video without HDR tone mapping, so colors can look flatter than on the phone.

Good to know

Quick answers about mov to mp4 in your browser.

Not here. The tool re-encodes the video to H.264 so the result is broadly compatible. At a low CRF the difference is hard to see, but it is a new encode rather than a straight copy of the original stream.

Phone videos are often 4K at high frame rates, and the encoding runs in WebAssembly inside your browser, which is slower than a native desktop app. Long 4K clips also need a lot of memory.

Yes. There is no sign-up, no watermark and no limit on how many files you process.

No. Files are read and processed locally in your browser, so they never leave your device.

Large files are slow in WebAssembly and must stay under 2GB.
