How to Compress Videos on Mac

Compressing videos on a Mac is an important task for anyone who wants to save storage space or share videos online. In this blog post, we’ll discuss what video compression is, the factors that affect it, and the different software options available for compressing videos on a Mac.

What is Video Compression and How it's Works ?

Reducing the size of video files while keeping the quality the same is called video compression. It removes unnecessary information and uses smart encoding methods. This allows the compressed videos to take up less storage space while still keeping the important visual details and sound. The resulting compressed video files are smaller and easier to stream online or share with others.

Software Options for Compressing Videos on Mac

There are a few different options for compressing videos on a Mac computer. You've got iMovie and QuickTime Player, which both come pre-installed on all Macs. Then there are options like Movavi and UniConverter, which are programs you can download. I'd probably start with iMovie or QuickTime Player since they're free and built right in. If for some reason those don't work for you, there are paid programs like Movavi and UniConverter that are specifically designed to compress video files and reduce their sizes.

Compress Videos Using iMovie to Compress Videos 

iMovie is a handy video editing app that can also shrink long videos down to a more manageable size. Here are the simple steps to compress a large video using iMovie:

1. Open the iMovie app on your Mac.

2. As iMovie opens up, now import your video. Click 'File' then 'Import Media'. And after that choose the video that you want to compress.

3.  As the video opens up, Click 'File' then 'Share' then 'File'.

4. In the export window, select the resolution you want. And then click on Quality & select Custom & Choose a smaller resolution from the dropdown menu and click 'Next'.

5. Choose where you want to save the compressed video and click 'Save'.

How to Compress a Video: Smart and Easy Way

1. Open QuickTime Player.

2. As it opens up, click on the "File" at the top menu bar & click Open File. After that simply open the video that you want to compress.

3. As the video opens up, again tap on the File option then Export As then 480p. This will export a 480p version with medium settings.

4. Choose where you want to save the compressed file and click Save. The compressed video will now be exporting.

QuickTime Player makes it easy to shrink large video files so they take up less space and are easier to share. Follow these simple steps to compress your video right from the QuickTime Player application already on your Mac.

Online Tools for Compressing Videos

In addition to software options, there are also online tools available for compressing videos. One such tool is Clideo, which allows you to upload your video and choose from several compression options.

What are the effects of video compression?

  • A few things have an impact on how much you can squeeze a video down in size, like the resolution, bitrate, and encoding type.

  • The resolution is basically how many tiny dots or 'pixels' make up each video frame. Videos with more pixels show more detail but take up a lot more storage.

  • The bitrate is the amount of information used for each second of the video. Videos with higher bitrates look better quality but the files get huge.

  • Encoding is what changes the original raw video data into a compressed format. Different encoding methods give you different amounts of file size reduction.


To save space and share videos more easily, you should trim down videos on a Mac. Video compression programs are available for Mac. You can shorten and reduce the file size of videos on Macs by using iMovie and QuickTime Player. Alternatively, you can use Movavi and UniConverter to control the compression settings. It only took a few minutes and the quality remained good.
