Top 4 Ways to Blur Out a Part of Picture on Mac

You’ll need to blur out confidential and private information on a picture before sharing it on a social media, group, or company channel. It’s essential to hide your phone number, email, address, or other vital details in your photo. You can blur or pixelate such details using the default Photos app or third-party tools on Mac. Let’s check them out.

Although the default Preview app is quite feature-rich, it doesn’t allow pixelating private info on a photo. You can use third-party apps to hide essential details in an image. We have picked the best tools to complete the job among the dozens of such apps. Here’s how to blur out part of a picture on Mac.

1. Photos App

Step 1: Open Finder on your Mac. Launch the Photos app too.

Step 2: Drag and drop the picture from Finder to the Photos app. Open the picture.

Step 3: Click Edit at the top-right corner.

Step 4: Expand the Retouch tool.
