How to crop a picture on Mac

5 min read

Many people think they need expensive apps like Adobe Photoshop for cropping pictures on Mac. It’s not true; even your Mac’s basic photo editing tools can handle image adjustments like cropping or rotating photos.

We should all familiarize ourselves with how to edit, resize, and trim our images on the Mac. When you know how to crop photos on Mac, you can edit the aspect ratio or size to suit any need. It’s also handy for social media; apps like Instagram may cut things you want to leave in the image. Cropping your own perfect square is a much better option!

Here we’ll tell you how to crop an image on Mac, how to crop a photo in Preview, and discuss why it’s important to know how to adjust images manually rather than relying on an algorithm or platform.

Tips to remember while cropping

Before we get into how to crop in Preview and with native apps, there are a few tips to keep in mind before adjusting any image:

  • Make a copy. It’s highly recommended you create a duplicate of the image you’re about to edit. If you make a mistake, at least the changes you made weren’t to the original! You may also want to make multiple copies of the source image just in case.
  • Adjust before you crop. When you want to crop an image on Mac, chances are you’re focused on the act of trimming the picture and losing sight of the rest. When an image is cropped, it can change the pixel density. We suggest any edits – like tint, color, or balance – be made before you actually crop the image to ensure the cropped image is as gorgeous as you want it to be.
  • Make small changes. It’s better to make small, incremental changes than try to go for gold on the first edit. When cropping pics on a Mac, adjust the borders of the crop area slowly. You can continue editing an image right up until you save your changes.
  • Don’t click save or confirm your actions until you’re sure. As you edit an image, the app is noting your changes but won’t commit to them until you click ‘save’ or the ‘crop’ button in Preview. Know that once you click the option to save the image you’re editing, all changes are final.

How to crop pictures in the Photos app

Before you edit an image using the Photos app, keep two things in mind:

  • If you add an image to Photos, it’s a copy. The above step will create a copy of the image in Photos. The image will still be in Finder, unchanged. If you forget to make a copy in Photos, don’t worry – there’s still the original in Finder.
