How to convert MOV to MP4 on a Mac

Drop the videos on Convert Video and choose MP4, or select them in Finder and use Quick Actions › OMT: Convert Video to MP4. It converts a whole batch on your Mac into new copies; the originals stay as they are.

Steps

  1. Select the MOV files in Finder, then right-click › Quick Actions › OMT: Convert Video to MP4. Or open OneMacTools › Convert Video and drop them in.
  2. In the app, choose MP4 as the format.
  3. Click Convert. The MP4s land in Downloads › OneMacTools, and the originals are untouched.

When the file is too big to send

Converting keeps the quality. To fit an email or chat limit, use Compress Video to Size instead: give it 25 MB, say, and it makes the best-looking MP4 that fits.

Every time, automatically

Make a Watch Folder for the folder where screen recordings or AirDropped videos land, with Convert Video to MP4. Each new video is converted as it arrives.

Questions

Is MOV worse than MP4?

Not in quality: both are containers, often with the same video inside. MP4 simply opens in more places, like Windows, Android and many websites.

Does converting reduce the quality?

OneMacTools converts at high quality. If you also need a smaller file, Compress Video or Compress Video to Size trade a little quality for size.

Can I convert many videos at once?

Yes. Drop a whole folder; they're converted one after another and you can keep working.
