Making a perfect photo is hard – even professionals don’t always get the frame they want on the first try. That’s why it’s pretty common to slightly change the dimensions of the photo (or another image) in post-production and exclude some parts that spoil the impression or reveal too personal details. Even if the original image author may be happy with the scope, other users might still find it useful to crop out some of the elements located near the edges.

If you are using a Mac computer, you have a choice of image editing tools that support the cropping function. Of course, the procedure is slightly different depending on the chosen tool, but in general, this is something you can learn how to do in the afternoon. This article could be a good starting point for beginners looking to become more skilled with image editing and help users with cropping images on a Mac regardless of the source from which they originally arrived.

What is Image Cropping and Why Is It Important?

To put it simply, cropping consists of cutting parts of the image out of the frame. This simple operation removes portions of the image located on the periphery, and can consequently change the dimensions and proportions of the image. Thus, even a relatively minor crop can completely alter the visual look and feel of the image, inspire a different interpretation, or make the image suitable for a different type of use (i.e. publishing on social media).

Since cropping doesn’t require practically any graphic design knowledge, it is one of the first editing operations that users learn how to do on a Mac. This can be a great way to cut random objects out of your photos, remove open tabs from your desktop screenshots, or isolate segments from images downloaded from the internet. Mastering this simple edit gives you the power to manipulate images in many different ways, which is why you should invest some time and practice until you get it right.

Frequently Asked Questions about Cropping Images on a Mac

Is manual cropping difficult to do with precision?

Since cropping is performed along straight lines and all cropping tools show you exactly where the line is, you don’t need to have great eye-hand coordination to do it with precision. That said, it’s still a good idea to zoom in before cropping and make sure that all the important details will remain in the picture.

Are there keyboard shortcuts I can use for image cropping on a Mac?

It’s possible to use the combination of keys CMD + K after you open an image with the Finder app to crop some parts of it. However, even with this method you still need to use your mouse to mark the area that should be cut from the picture, so the shortcut doesn’t save a whole lot of time.

Should I delete the old version of the image after I saved a cropped version?

In case you are just trimming the background and the new version is unquestionably better than the raw original, there is no need to keep the old version on the Mac. On the other hand, if you cropped out some relevant details (i.e. phone numbers or e-mail addresses) for specific reasons, you probably shouldn’t delete the original image.
