How to Crop an Image on Mac: A Step-by-Step Guide

Cropping an image is a common task that many of us need to do from time to time, whether it’s for social media, presentations, or simply to improve the composition of a photo. If you’re using a Mac and wondering how to crop an image, you’re in the right place. In this guide, we’ll walk you through the steps to crop an image on your Mac.

Using Preview to Crop Images on Mac

One of the easiest ways to crop an image on a Mac is by using the built-in Preview app. Here’s how you can do it:

1. Open the Image: Start by opening the image you want to crop in the Preview app. You can do this by double-clicking on the image file or right-clicking and selecting “Open With” > “Preview.”

2. Select the Crop Tool: In Preview, click on the “Show Markup Toolbar” button at the top of the window (it looks like a toolbox). Then, click on the “Crop” icon in the toolbar, which looks like two overlapping right angles.

3. Adjust the Crop Box: Click and drag on the corners and edges of the crop box to adjust it to your desired size and position. You can also move the entire crop box by clicking and dragging inside it.

4. Apply the Crop: Once you’re happy with your crop selection, press Enter or click on “Crop” in the toolbar to apply the crop.

5. Save Your Cropped Image: Finally, go to File > Save (or Command + S) to save your cropped image.

Using Third-Party Apps for Advanced Cropping

While Preview is great for basic cropping needs, if you’re looking for more advanced features or options, you may want to consider using third-party apps like Adobe Photoshop or GIMP (GNU Image Manipulation Program). These apps offer more advanced editing tools and capabilities for cropping images.


Cropping an image on a Mac is a simple process that can be done using built-in tools like Preview or more advanced third-party apps like Photoshop or GIMP. Whether you need basic cropping functionality or more advanced editing options, there’s a tool out there that can meet your needs.
