3. Compress MOV File on Mac in QuickTime Player

Mac users? You're in luck as you can use the pre-build QuickTime Player to reduce MOV file size on Mac for free.

Though I have to admit this media player has a very limited range of compression features. With it, you can't enter the exact bitrate value or frame rate value to make a .mov file smaller. From our test, QuickTime Player can work without errors only when being used to decrease MOV (MPEG-2/4 and H.264) files. Worse still, compressing a .mov file on Mac via QuickTime Player somewhat will cause horrible quality loss.

Step 1. Launch up QuickTime Player on your Mac.

Step 2. Press File on the top menu bar to find Import. Click this to feed the MOV file to QuickTime Player.

Step 3. Navigate to the menu bar and choose File again. Choose Export As from the drop-down menu of File.

Step 4. From the 5 options (4K, 1080P, 720P, 480P, and audio only), select the one that is lower than the original resolution.

4. Compress a MOV File on Mac in iMovie

Mac users can also take advantage of iMovie to compress MOV file size for free. This easy video editor can reduce the MOV file to half to the original size or even smaller. However, it is not the perfect solution to condense the MOV file for two reasons. In a nod to beginners, iMovie simplified the quality control options a lot, offering you only rough options like Low, Faster, and Medium to downsize the MOV file.

Besides, iMovie is a CPU-oriented program that might take around 90% of your CPU resource to compress MOV file to a smaller size. Anyway, let's take a look at the answer to how do I reduce the file size of a .MOV in iMovie.

Step 1. Open up iMovie. Press Project, click on the plus button on the top left of the window, and then you select Movie. Choose No Theme on the pop-up query box. Afterward, select Create.

Step 2. Drag and drop the file that comes with .mov as the extension name to iMovie.

Step 3. Press File on the top menu bar, choose Share and select Export File.

Step 4. Now you've come to the setting panel for your video. There are 4 options to shrink the MOV file size.

Step 5. According to your demand, you can choose a resolution lower than the original MOV file; pick the desired quality level since the higher quality level equals a larger file size; set Faster as the compressed mode.

Step 6. Choose Next. Enter the name for the output file and define an output file folder. Next, you press Save. iMovie starts helping you reduce MOV file size on Mac.

6. Compress MOV Files Online in PS2PDF

PS2PDF Video Compressor offers a flexible way for people to compress MOV files online for free. The feature I love most about this online toolkit is it allows you to reduce the MOV file size by percentage. Surely, you can still adjust the resolution and constant rate factor to get a high quality compressed MOV file.

Unfortunately, PS2PDF cannot compress large MOV files. From our test, it won't recognize a MOV file with a size larger than 250MB. Another disappointing thing is the support of MOV output is absent. The extension of the video file will change from .mov to .webm or .mp4 after the compression.

Step 1. Visit the official site of the PS2PDF compressor on your browser, press File.

Step 2. Choose Select From Disk, Select From Dropbox (Fast), or Select From Google Drive (Fast) to import the MOV to the online MOV compressor from local disk, Dropbox, or Google Drive.

Step 3. Choose MP4 or WBEM as the output file container and select H.264 as the video codec.

Step 4. On the setting panel of Output Quality And File Size, you can make some adjustments for a better yield out.

  • Choose By Percentage as File Size, move the cursor on the quality slider to adjust the compression ratio.
  • Choose By Preset Quality, select the favored preset to shrink the MOV. A faster preset usually refers to a smaller outcome video size. You'll also need to assign a proper value for Content Rate Factor. Note: the smaller the content rate factor value, the slower the MOV compression speed.

What Is a MOV File?

Wonder what is a MOV file or is QuickTime movie the same as MOV? Below information might shed up a light for you.

  1. Apple initially created MOV in 1998 as a container format to use in QuickTime player.
  2. A MOV file or the file with .mov as the extension is QuickTime(QT) file format.
  3. The data inside a MOV file might include video compressed in codecs like HEVC, MPEG-4, and H.264/AVC, audio codec compressed in codecs like AAC and MP3, and countless other media data.

Why Is My MOV File So Big?

MOV is a video container format which has nothing to do with the final file size. The thing that makes your MOV file large is the media data inside the capsule. A MOV can hold video data encoded by the advanced lossy codec like HEVC and H.264, the lossless codecs like Motion JPEG, and the low compression efficient codecs like Apple ProRes and Cinepak. Since the big file size is one of the key features of the latter two codecs, it's no surprise your MOV file is bulky.
