Do you want to learn how to edit a picture on Mac? Look no further!

In this article, we will guide you through the steps to edit your photos using the built-in Photos app on your Mac. Whether you are a beginner or an experienced user, these tips and tricks will help you enhance your images and bring out their full potential.

Step 1: Opening the Photos app

To begin editing your picture, locate and open the Photos app on your Mac. You can find it in the Applications folder or by using Spotlight search (press Command + Space and type “Photos”). Once opened, you’ll see your photo library displayed in the main window.

Step 2: Selecting a picture

Select the image you want to edit by clicking on it. This will open the picture in its own window, allowing you to focus solely on editing it.


If you want to make basic adjustments to your photo’s exposure, color, or contrast, click on the “Adjustments” button located at the top of the window. This will reveal a range of tools for fine-tuning your image.

  • Brightness: Use this slider to increase or decrease the overall brightness of your photo.
  • Contrast: Adjust this slider to increase or decrease the difference between light and dark areas in your image.
  • Saturation: Use this tool to make colors more vibrant or subdued by adjusting their intensity.

You can experiment with these adjustments until you achieve the desired look for your photo. Remember that subtle changes often yield better results than extreme alterations!

Cropping and Straightening

If you want to crop your picture or straighten any tilted horizons, click on the “Crop” button located next to the “Adjustments” button.

  • Crop: Use the draggable corners of the cropping frame to select the portion of your image you want to keep. You can also adjust the aspect ratio or rotate the photo if needed.
  • Straighten: If your picture is slightly crooked, use this tool to align it with a straight edge in the photo.

Once you’re satisfied with your changes, click on the “Done” button to apply them.


If you want to quickly enhance your photo with pre-set filters, click on the “Filters” button located next to the “Crop” button. This will reveal a variety of filters, each providing a different mood or style for your image. Simply click on a filter to apply it instantly.

Step 3: Saving and Exporting

After editing your photo, it’s time to save and export it. To save your changes, press Command + S or go to File > Save. This will update the edited version in your photo library.

If you want to export the edited picture as a separate file, go to File > Export > Export [number] Photo(s). Choose a location where you want to save your image, select the desired file format (such as JPEG or PNG), and click on the “Export” button.


You have successfully edited a picture using Mac’s built-in Photos app. With these tools at your disposal, you can now unleash your creativity and transform ordinary photos into stunning works of art!

Remember, practice makes perfect, so don’t hesitate to experiment and try different editing techniques. Enjoy the process and have fun exploring the endless possibilities of photo editing on your Mac!
