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.
The easiest method for cropping a Mac screenshot is using the built-in screenshot cropping tool.
After you take a screenshot using the keyboard shortcuts Command + Shift + 3 (to capture a full screenshot) or Command + Shift + 4 (to capture a portion of your screen), follow the step below to crop the screenshot:
- A floating thumbnail of the screenshot will appear in the bottom-right corner of your screen - click on it.
- A cropping tool window will open.
- Click on the ‘Crop’ icon in the top-right corner.
- Drag the crop handles of the screenshot to select the area of the screenshot you want to keep.
- 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:
- After you take the screenshot, wait until it appears on the screen.
- Click on it to open it.
- Then drag the cursor to select the area you want to keep.
- Next, go to Tools > Crop.
- When you have the desired screenshot image, navigate to File > Save to save it.

- Click on the pencil icon in the top-right corner.
- Next, select the ‘Crop to selection’ button.
- Drap the crop handles to select an area to keep.
- If you’d like to undo the changes, select ‘Revert’ at the top right corner next to Done.
- Click on ‘Done’ in the top-right corner to save the cropped screenshot.
