How to Crop a Screenshot on Mac: Step-by-Step Guide

Cropping a screenshot on a Mac is a simple task that can be done in a few quick steps. First, take your screenshot using the ‘Command + Shift + 4’ keys, which will turn your cursor into a crosshair. Then, click and drag to select the area you want to keep. Release the mouse or trackpad button to capture the screenshot. Finally, find the screenshot on your desktop and use the ‘Preview’ app to make any further edits, such as cropping or resizing.

Step by Step Tutorial: How to Crop a Screenshot on Mac

Before you can crop a screenshot on your Mac, you need to take one. The following steps will guide you through the process from capturing the screen to cropping it to your desired size.

Step 1: Capture the screenshot

To take a screenshot on a Mac, press the ‘Command + Shift + 4’ keys simultaneously. Your cursor will change to a crosshair symbol.

After pressing the key combination, your screen will dim slightly and your cursor will turn into a crosshair. You can then click and drag to select the portion of the screen you want to capture. When you release the mouse or trackpad button, the screenshot will be taken and saved to your desktop by default.

Step 2: Open the screenshot

Locate the screenshot on your desktop, which is usually labeled with the date and time it was taken. Double-click the file to open it in the ‘Preview’ app.

The ‘Preview’ app is the default image viewer on Mac computers. It’s not just for viewing images, though; it also has a range of editing tools, including the ability to crop screenshots.

Step 3: Select the crop tool

In the ‘Preview’ app, click the ‘Show Markup Toolbar’ button (it looks like a little pencil). Then, select the ‘Rectangular Selection’ tool from the toolbar.

The ‘Rectangular Selection’ tool allows you to click and drag to create a box around the area of the image you want to keep. Once you’ve made your selection, you can move or adjust it as needed.

Step 4: Crop the screenshot

After making your selection with the ‘Rectangular Selection’ tool, click the ‘Crop’ button (it looks like two overlapping right angles) to crop the screenshot to the selected area.

The ‘Crop’ button is also located in the ‘Markup Toolbar’. Once you’ve clicked it, everything outside the selection box will be removed, and you’ll be left with just the part of the screenshot you want to keep.

Step 5: Save the cropped screenshot

To save the changes you’ve made, go to ‘File’ in the menu bar and select ‘Save’. You can also choose ‘Save As’ if you want to keep the original screenshot and save the cropped version as a new file.

Remember to save your edited screenshot, or all your hard work will be for nothing! You can save it in a variety of formats, including JPEG, PNG, and PDF.

After completing these steps, you’ll have a neatly cropped screenshot ready to be used however you need. Whether it’s for a presentation, a report, or just to share with friends, your Mac makes it easy to capture and edit screenshots.
