How To Compress a Video On Mac

With the rise of 4K and UHD video technology, both storing and sharing your videos is becoming more difficult. Large video clips can be hard to manage, and they’re more difficult to transfer if your Mac runs out of space. 

If you often have a problem with storing or sending large videos, you should learn how to compress your video files on your Mac. There are plenty of apps and tools that can help you do that. 

How to Compress a Video on Mac

Your Mac comes with built-in tools that you can use to compress a video. For example, iMovie or QuickTime Player. While they might be somewhat limited in functionality, there’s an obvious advantage here since you don’t need to download or pay for them. 

If you’re looking for more functionality, try one of the third-party options from our list. Some of them you’ll need to download, like Handbrake or Movavi, while others you can use online via your browser. 

iMovie

iMovie is a popular built-in tool on Mac that you can use not just for video compression but for video editing in general. This software makes the process of compressing a video free and easy. To shrink a video using iMovie, follow the steps below.

1. Open the iMovie app on Mac.

1. Select the Create New icon to create a new project. 

1. Use the File menu to Import Media or drag and drop your files right into the app. 

1. To compress the video, go to the File menu and select Share. 

1. Depending on your goal, select one of the available options. You can choose to compress the video specifically for sending it via email or select the File option to set the desired quality and resolution yourself. In the same window, you’ll also see the size of your exported video. 

1. Once you’re happy with your video settings, select Next… to save the clip. Select the location for your file on your Mac and select Save. 

QuickTime Player

QuickTime Player is considered one of the top media players and one of the best apps for Mac overall. It’s also an excellent built-in option for shrinking your videos on Mac. To compress a video using QuickTime Player, follow the steps.

1. Open the QuickTimePlayer app on your Mac. 

1. Navigate to the video that you want to compress and open it.

1. From the app’s ribbon menu, select File > Export As. Here you’ll get a variety of options to choose from, like exporting your file in 4K, 1080p, 720p, 480p, or exporting audio-only. 

1. Once you’ve selected the desired quality, type in the name for your video under Export As, select the destination, and select Save. 

You can then compare the sizes of both your imported and exported videos via right-click and Get Info option to see how much your original video shrank. 

HandBrake

HandBrake is an open-source video converter that you can use to convert your video clips from pretty much any format to widely supported codecs. On top of that, you can use the app to shrink your video files. All you need to get started is to download the software for free. Then, to compress a video using HandBrake follow the steps below.

1. After you download and install the app, launch HandBrake on your Mac.

When this is complete, you’ll see the Encode Finished message appear in the app. You’ll find your compressed video in the destination you selected earlier. 

Movavi

Movavi is another useful video editor that you can use for free to compress a video on Mac. It’s beginner-friendly and has an intuitive interface. So if you don’t have any video editing experience, this is a great tool to use.

Follow the steps below to compress a video using Movavi.

1. Download, install and open the app on your Mac. 

1. Drag your video clip into the app or click the Plus icon to add it.
