How to convert MOV to MP4

  1. Drop the MOV in. iPhone videos, Mac screen recordings, Final Cut exports.
  2. Choose a size, or keep it as it is. Format is already set to MP4. "Best quality" keeps it looking the same; "Balanced" or a target size shrinks a big iPhone clip for sharing.
  3. Download the MP4. Plays in Windows Media Player, on Android, in every browser and on every upload form.

Why MOV files cause trouble

Windows and Android
MOV is Apple's container. Many Windows and Android players refuse it or play it without sound. MP4 plays everywhere.
HEVC from newer iPhones
iPhones record in HEVC by default, which older devices and many web players cannot decode. The MP4 here comes out as H.264, which everything plays.
Upload forms and platforms
Course platforms, job applications and CMSs often accept MP4 only. Converting takes a minute.

The iPhone file size problem

  • A minute of 4K from an iPhone is around 400 MB in HEVC and larger in H.264. Pick a target size for WhatsApp, Discord or email and the MP4 comes out under the limit, at 1080p, which is what those apps show anyway.
  • For an edit or an archive, keep "Best quality" and the original resolution.

Questions people ask

Does MOV to MP4 lose quality?

With "Best quality" the video keeps a high quality that is visually identical. Picking a smaller size trades quality for size on purpose, at the level you choose.

Why does my iPhone video have no sound on Windows?

Older Windows players lack the codecs for MOV and HEVC. The MP4 from this tool uses H.264, which Windows plays out of the box.

Will the MP4 be smaller than the MOV?

About the same size or a little smaller with "Best quality". Choose "Balanced" or a target size to make it clearly smaller.

Can I convert MP4 to MOV?

Yes, on the MP4 to MOV page.

How long does it take?

Short phone clips take moments. Long 4K videos take longer, and go faster on a recent computer.

Is there a watermark?

No.
