Why Crop Pictures on Mac?

Ever snapped a photo and later thought, 'If only I could just trim out that little bit?' You’re not alone. Cropping pictures can bring focus to the subject, remove unwanted elements, or simply fit your needs better. Let's dive in.

Using Preview to Crop Pictures on Mac

Open Your Image in Preview

Preview is the default app for viewing images on Mac. Simply double-click your image, and it should open in Preview.

Select the Crop Tool

  1. Click the 'Show Markup Toolbar' button located in the top bar (it looks like a pencil tip inside a circle).
  2. Use the selection tool to draw a rectangle around the area you want to keep.

Crop the Image

  1. Once your selection is made, go to 'Tools' in the menu bar.
  2. Click 'Crop.'
  3. Save the image by going to 'File' > 'Save.'

Using Photos App to Crop Pictures on Mac

Open the Photos App

Open the Photos app from your Applications folder or by clicking its icon in the Dock.

Choose Your Photo

Find the image you want to crop and double-click to open it.

Use the Edit Button

  1. Click 'Edit' in the upper right corner.
  2. Click 'Crop' in the toolbar that appears.

Adjust and Save

  1. Adjust the crop box by dragging the edges or corners.
  2. Once satisfied, click 'Done.'
  3. The cropped image will be saved automatically.

Tips for Better Cropping

  • Maintain Aspect Ratio: Most apps like Preview and Photos offer an option to lock the aspect ratio while cropping. This is great for keeping things proportional.
  • Use Gridlines: Some apps show gridlines to help you align your crop better. Use them to your advantage.
  • Zoom In: Zoom in for precise adjustments.
