How to convert MOV to MP4 on Mac
Right-click the MOV file in Finder and choose FileMate › Compress Video. FileMate saves an MP4 copy next to it, re-encoded in HEVC, or H.264 if you choose Most Compatible in Settings. It’s also smaller, which is usually what an upload form needs next. QuickTime Player always saves MOV, but iMovie can export MP4 with File › Share › File.
The video is converted on your Mac, without an upload.
Get an MP4 with FileMate
- Right-click the .mov file in Finder.
- Choose FileMate › Compress Video.
- Clip compressed.mp4 is saved next to Clip.mov.
FileMate keeps a copy only when it’s meaningfully smaller than the original. For an already small, efficient MOV, it may report “Already well compressed” instead of saving an MP4.
MOV and MP4: what’s the difference?
Both are containers: they hold the video and audio, encoded with a codec such as H.264 or HEVC. MOV is Apple’s format, used by iPhone, QuickTime and screen recordings. MP4 is the international standard, and it’s what most websites, Windows PCs, Android phones and upload forms expect.
The video inside a MOV is often exactly the kind MP4 can hold, which is why some apps accept either. When a site insists on .mp4, the file has to be written as MP4.
HEVC or H.264?
| Codec | Size | Plays on |
|---|---|---|
| HEVC (H.265) | Smaller at the same quality | Apple devices, recent Windows and Android, many browsers |
| H.264 | Larger | Practically everything |
FileMate uses HEVC by default. If the video is going to a school portal, an older PC or someone whose device you don’t know, set Most Compatible in FileMate Settings › Compression.
With iMovie
- Create a project in iMovie and add the MOV.
- Choose File › Share › File.
- Choose the resolution and quality and export. iMovie saves an MP4.
It works, and iMovie is free. It takes a project for every video and more steps than a right-click.
What about Finder’s Encode Quick Action?
Encode Selected Video Files saves an .m4v. That’s an Apple variant of MP4 that most players open, but forms that check for .mp4 may reject it.
Get FileMate
MOV in, smaller MP4 out, from the right-click menu. FileMate does it on your Mac, however large the video is.
