Removing the background from an image can enhance the visual appeal and focus on the subject, making it an essential skill for designers, marketers, or anyone working with images. Whether you're looking to create professional graphics or simply clean up photos for personal use, macOS offers various tools and methods to achieve stunning results. In this comprehensive guide, we'll walk you through the process of removing backgrounds using both built-in applications and third-party software.
Understanding the Importance of Background Removal
Before diving into the specifics, it’s crucial to understand why background removal is significant.
- Improved Focus on the Subject: By eliminating distractions, the viewer's attention is drawn to the subject.
- Versatility for Various Projects: Clean images are ideal for presentations, social media, and marketing materials, allowing for more creativity.
- Consistency in Branding: A cohesive visual identity is essential in branding, and removing backgrounds helps maintain this consistency.
- Professional Quality: High-quality images can set your work apart, whether it’s for personal or business purposes.
Now that we've established the importance, let’s explore the various ways to remove backgrounds on macOS.
1. Using Preview: The Built-in Solution
Preview is the default image viewer on macOS, and it offers a surprisingly powerful set of tools for image editing. While it may not have the advanced features of some dedicated software, it's quite effective for basic background removal tasks.
Step-by-Step Guide to Remove Background Using Preview
-
Open the Image: Right-click your image file, select “Open With,” and choose “Preview.”
-
Select the Markup Tool: Click the “Markup” button (which looks like a pencil icon) in the top toolbar.
-
Use the Instant Alpha Tool: This tool allows you to select colors and areas of the image based on color similarity.
- Click and hold the mouse over the area you want to remove (the background). Drag left or right to adjust the selection area.
- You’ll see a highlighted area as you adjust. Be careful not to include parts of your main subject.
-
Remove the Background: Once you have the desired area selected, press the Delete key on your keyboard. The selected background will be removed, leaving you with a transparent area.
-
Save Your Image: To keep the transparent background, ensure you save the file in a format that supports transparency, such as PNG.
Limitations of Using Preview
While Preview is a handy tool, it does have limitations:
- It’s not ideal for intricate images with complex backgrounds.
- The selection process can be less accurate for images with multiple colors.
Despite its limitations, Preview is a quick solution for simpler images, and it showcases the power of built-in tools on macOS.
2. Using Photos App for Quick Edits
The Photos app on macOS also provides tools for editing images, including background removal. This is particularly useful for users who regularly organize and edit their photos.
Steps to Remove Background in Photos App

Open Photos App: Find and launch the Photos app from your Dock or Applications folder.

-
Outline the Subject: Use the selection tool to outline the subject of your photo.
- Adjust the selection points as necessary to ensure you are capturing just the subject.
-
Confirm and Remove the Background: Once satisfied with your selection, confirm it. The area outside the selection will be removed, leaving only your subject.
-
Save Your Work: Save the edited version of your photo by clicking the “Done” button.
Benefits of Using the Photos App
- User-Friendly: This method is intuitive and well-integrated with the macOS environment.
- Integrated Features: You can use other editing features in conjunction with background removal, such as cropping and filters.
However, similar to Preview, the Photos app may struggle with complex backgrounds and detailed images.
3. Using Keynote for Precise Background Removal
Keynote, the presentation software from Apple, includes some powerful image editing tools that can also be used for background removal. This is particularly useful if you want to create visually stunning slideshows.

Finish and Save: Once satisfied, you can export your slide as an image. Choose “File” → “Export To” → “Images” to save it in your desired format.
Pros and Cons of Keynote for Background Removal
- Pro: More precise than Preview and Photos app for complex backgrounds.
- Con: It may take a little time to get used to, especially for users unfamiliar with Keynote.
This method is a great workaround if you need a more detailed approach without installing new software.
