How to Redact an Image: Full Guide on How to Blur and Hide Text in Screenshots with Ease

If you’ve ever shared a screenshot only to realize you missed something sensitive, you know how important it is to redact images properly. Whether it’s personal information, confidential data, or simply a mistake, knowing how to blur or black out text in screenshots is a crucial skill for protecting privacy. Luckily, both macOS and iOS offer powerful tools to redact screenshots, making it easy to ensure that your images are safe to share.

In this article, we’ll explore various methods for redacting images and show you how to blur text in screenshots using built-in macOS tools, third-party apps, and advanced features available on both Mac and iPhone.

Why Redact an Image?

Redacting an image is all about protecting sensitive data. Screenshots often capture more than you realize—personal details, financial information, and even passwords might be unintentionally shared. By redacting, you can ensure that this information stays private.

Here’s why you might need to redact an image:

• Protect your privacy: Prevent accidental sharing of sensitive information.
• Professionalism: Redacting screenshots is the industry standard for sharing documents, legal files, and communications.
• Legal and business contexts: Redacting ensures that confidential or proprietary data is not exposed to unintended recipients.

Let’s explore the top tools you can use to blur and redact text in your images!

1. Using Preview to Black Out Sensitive Information on Mac

For those who need a quick and simple way to redact images on Mac, Preview is the built-in option. While it lacks advanced blurring functionality, you can easily block out sensitive text or data using shapes.

How to redact with Preview:

1. Right-click the screenshot and choose Open With > Preview.
2. Go to Tools > Annotate and choose a shape (e.g., rectangle).
3. Drag the shape over the area you want to redact.
4. Adjust the color of the shape (choose black or a neutral color for a clean look).
5. Save the file.

Preview is great for basic redactions and quick edits, but it doesn’t offer advanced blurring options.

Pros:

• Built-in on macOS, no need to download additional software.
• Quick and easy to use for basic redactions.

Cons:

• Lacks the ability to blur text or apply advanced image editing.
• Not ideal for complex images or documents.
