Blur Images on Mac for Stunning Visual Effects in Photos.

Blurring images on a Mac is a crucial step to protect sensitive information before sharing photos online. Here are several methods to blur images using both built-in and third-party tools.

Using Skitch to Blur Images

Skitch, part of the Evernote family, is a versatile tool for editing images on your Mac.

• Launch Skitch: If you don't have Skitch, you can download it from the Mac App Store. Otherwise, launch the app from your Applications folder.
• Load the Image: Drag and drop the image you want to edit into Skitch, or go to "File -> Open" to load it.
• Select the Pixelate Tool: On the left side of the app, find the "Pixelate" tool, which is the second-to-last option in the vertical toolbar. It can be identified by its blurry or pixelated icon.
• Blur the Image: Use your mouse to drag the cursor over the area you want to blur. This tool works as a square or rectangle, and you can go over the area multiple times to ensure it is fully blurred.
• Save the Image: Once you've blurred all the necessary areas, save your work by going to "File -> Export" and choosing a location on your Mac's hard drive. Alternatively, you can drag and drop the image from the Skitch app to a file folder or desktop.

Using the Photos App to Blur Images

While the Photos app doesn't offer a traditional blur tool, you can use the Retouch tool to achieve a similar effect.

• Open the Photos App: Launch the Photos app on your Mac and open the image you want to edit. You can drag and drop the image into the app or go to "File -> Import" to add it.
• Edit the Image: Double-click the image to enter edit mode, and then click the "Edit" button at the top-right corner.
• Use the Retouch Tool: In the edit screen, find the "Retouch" tool about halfway down on the right side of the app. Adjust the brush size as needed.
• Blur the Area: Drag the circular brush over the part of the image you want to hide. This tool will smudge the area rather than blur it, effectively hiding sensitive information.

Using Preview to Blur Images

Preview, a built-in app on Mac, can be used in conjunction with other tools to blur images.

• Open the Image in Preview: Double-click the image to open it in Preview.
• Use Markup Tools: Click the "Markup" icon (looks like a pen tip) in the upper right corner. In the Markup toolbar, select the "Square/Circle Shape" icon and choose a shape to cover the sensitive area.
• Add a Shape: Use the blue toggles to move and resize the shape over the sensitive information. This method doesn't blur but effectively censors the area.

Using iMovie and Preview for Advanced Blurring

For a more advanced blurring technique, you can use iMovie and Preview together.

• Open the Image in iMovie: Drag the image into iMovie and go to the "Transitions" tab. Drag a "Cross Blur" transition to the end of the photo.
• Find the Blurry Frame: Go to full screen, drag the cursor to the lower part of the screen to show the progress bar, and use the left arrow button to scroll frame by frame until you find a blurry frame.
• Take a Screenshot: Take a screenshot of the blurry frame using "Command + Shift + 4" and position the crosshairs to capture only the image.
• Open in Preview: Open the screenshot in Preview, go to "File -> Export," select JPEG format, and boost the quality to "Best."
• Combine Images: Open the original image in Preview, use the "Lasso Selection" tool to select the foreground, copy it, and paste it onto the blurred image. Adjust the size and position as needed, then save the final image.

Using Third-Party Tools like CleanShot X

For more advanced and precise blurring, you can use third-party tools like CleanShot X.

• Open CleanShot X: Open the CleanShot X app and select the image you want to edit.
• Choose Redaction Style: Click the "Redaction style button" and choose "Pixelate," "Blue," or "Black Out."
• Blur the Area: Use the tool over the sensitive portion of the image, adjusting the sensitivity as needed.
• Save the Image: Click "Save As" and save the image. This method provides more control over the blurring process.

By using these methods, you can effectively blur images on your Mac to protect sensitive information before sharing them online.
