How Can I Reduce the Size of a Video Without Losing Quality Mac?

If you are a Mac user, you may have found yourself in a situation where you need to reduce the size of a video without losing its quality. This can be particularly useful when you need to upload a video online or share it with someone via email, and the file size exceeds the maximum limit.

Fortunately, there are several ways to achieve this without compromising the video quality. In this article, we will explore some of these methods.

Method 1: Compress the Video Using QuickTime Player

QuickTime Player is an excellent tool for playing and editing videos on a Mac. It also comes with a built-in compression feature that allows you to reduce the size of your videos without sacrificing their quality. Here’s how to do it:

  1. Open QuickTime Player on your Mac.
  2. Click on “File” in the top menu bar and select “Open File. “
  3. Select the video file that you want to compress.
  4. Once the video file is open, click on “File” again and select “Export As.

  5. In the Export window, choose “480p” or “720p” from the Resolution drop-down menu. These options will reduce the size of your video without significantly affecting its quality.
  6. Select an output destination and click on “Save. “


  • The above method works best for videos that are already in high definition (HD) format.
  • If your video is not in HD format, choosing a lower resolution may result in significant loss of quality.

Method 2: Convert Video Using HandBrake

HandBrake is another popular tool for compressing videos on Macs. It is a free, open-source video transcoder that can convert videos to different formats and compress them without losing quality. Here’s how to use HandBrake to compress your video:

  1. Download and install HandBrake on your Mac.
  2. Open HandBrake and click on the “Source” button in the top menu bar.
  3. Select the video file that you want to compress.
  4. Choose a preset from the right-hand side of the window. A preset is a pre-defined set of options that will optimize your video for specific devices or purposes.

    For example, you can choose a preset for Apple TV, iPhone, or Android devices.

  5. Adjust the settings as needed. You can change the resolution, bitrate, and other settings to reduce the size of your video further.
  6. Click on “Start” to begin the conversion process.
  • The conversion process may take some time depending on the size of your video file and the quality settings you choose.
  • The resulting file may be in a different format than your original video file.

Method 3: Use Online Video Compressor Tools
