Do you have a bunch of JPEG images on your Mac that are too large in size? Resizing them can save you valuable disk space and make it easier to share them with others.

In this tutorial, we will guide you step by step on how to resize JPEG images on your Mac. Let’s get started!

Method 1: Using Preview

The Preview app on your Mac is not just for viewing images; it also offers basic editing capabilities, including resizing. Follow these simple steps:

  2. Select the “Adjust Size” option: In the top menu bar, click on “Tools” and then select “Adjust Size.”

    Alternatively, you can press Command + Option + I as a shortcut.

  3. Set the desired dimensions: In the pop-up window, you can specify either a custom width or height for your image. Make sure to maintain the aspect ratio by enabling the checkbox next to “Scale proportionally. “
  4. Save the resized image: Once you are satisfied with your new dimensions, click on “OK.” To save your changes, go to “File” in the top menu bar and choose “Save” or use Command + S.

    You can also choose whether to replace the original files or create copies of them.
