If you want to capture part of your Mac screen to show what you are seeing to someone or demonstrate an on-screen activity, you can easily take a screenshot.

However, if you only need a portion of the screen, or you want to hide some sensitive information, Mac offers the option to crop your screenshots. In this post, we’ll show you how to crop a screenshot on Mac in several different ways.

5. Click on ‘Done’ to save the cropped screenshot image.

If you don’t see a thumbnail appearing at the bottom of the screen, you can access the cropping tool in another way:

1. After you take the screenshot, wait until it appears on the screen.
2. Click on it to open it.
3. Then drag the cursor to select the area you want to keep.
