When it comes to editing text in Google Docs, sometimes you need to highlight or obscure certain sections. Whether you're preparing a document for public viewing or just trying to keep some details private, learning how to black out a box in Google Docs can be a handy trick. In this post, we'll walk through the steps to achieve this effect, ensuring your sensitive information remains hidden from prying eyes.
Why Black Out Text?
There are numerous reasons you might want to black out text in your Google Docs. Perhaps you're sharing a draft with colleagues and want to keep some information confidential. Or maybe you're creating a document for public consumption but need to adhere to privacy regulations by redacting personal data. Whatever your reason, blacking out text is a practical skill that enhances your document management toolkit.
What makes this process even more appealing is its simplicity. You don't need to be a tech wizard or have sophisticated software. Everything you need is right there in Google Docs, ready for you to use. So, let's get started on how to make it happen!
Using the Highlight Feature
The first method, and perhaps the easiest, involves using the highlight feature in Google Docs. While this doesn't technically "black out" the text, it does create a similar effect using a dark color that makes the text unreadable.
- Step 1: Open your Google Docs document and select the text you want to black out.
- Step 2: Click on the "Text color" icon in the toolbar, which looks like an underlined "A."
- Step 3: Select the "Highlight color" option.
- Step 4: Choose black or any dark color from the palette. Your selected text will now appear "blacked out."
This method is straightforward and works well for small sections of text. However, if you're dealing with larger portions, or if you want a more secure blackout, you might need a different approach.
Drawing a Shape Over Text
For a more secure blackout, consider using the drawing feature in Google Docs to place a shape over your text. This method completely blocks out the text, leaving no room for accidental peeking.
- Step 1: Go to the "Insert" menu and choose "Drawing" followed by "+ New."
- Step 2: In the drawing window, select the "Shapes" icon and choose a rectangle.
- Step 3: Draw a rectangle, adjusting the size to cover your text.
- Step 4: Fill the shape with black using the "Fill color" tool.
- Step 5: Once done, click "Save and Close."
The shape will appear on your document as an overlay, effectively blacking out the text beneath. This method is more secure since the text is entirely covered by the shape.

Using the Image Editing Tool
If you need to redact text in an image within your document, Google Docs offers basic image editing tools that can help. Here's how to black out parts of an image:
- Step 1: Click on the image to select it.
- Step 2: Click on "Format options" in the toolbar, which appears as a sidebar.
- Step 3: Use the "Adjustments" option to darken the entire image, or use "Recolor" to add a black overlay.
While these tools are somewhat limited, they can be effective for simple tasks. For more complex image editing needs, you might consider using a dedicated image editor like GIMP or Photoshop.
Creating a Redaction Using Google Drawings
Google Drawings is another tool that integrates seamlessly with Google Docs. You can create a redaction overlay in Google Drawings and insert it into your document.
- Step 1: Open Google Drawings and create a new drawing.
- Step 2: Use the "Shapes" tool to draw a rectangle and fill it with black.
- Step 3: Save the drawing and insert it into your Google Docs document where needed.
This method provides flexibility and control over the size and placement of your redaction, making it ideal for precise tasks.
Redacting with Third-Party Add-ons
If you find the native options in Google Docs limiting, third-party add-ons can offer enhanced redaction capabilities. Add-ons like "DocSecrets" can encrypt and hide text within your document, providing a more secure option for sensitive information.
- Step 1: Go to "Add-ons" in your Google Docs menu, then click "Get add-ons."
- Step 2: Search for a redaction tool, such as "DocSecrets," and install it.
- Step 3: Follow the add-on's instructions to redact your text.
While using add-ons can enhance functionality, it's essential to ensure they're from reputable sources to maintain the security and privacy of your documents.
Printing and Scanning Method
An old-school method involves printing the document, physically blacking out the text with a marker, and then scanning it back into Google Docs. This method is cumbersome but effective if you need a physical copy with redacted information.
- Step 1: Print the document.
- Step 2: Use a black marker to redact the necessary sections.
- Step 3: Scan the document and upload it back to Google Docs.
This approach is best suited for those who prefer physical documents or require a permanent physical record.
Considerations for Redacting Text
When redacting text, it's crucial to consider the context and purpose of the redaction. Here are a few considerations:
- Purpose: Ensure that the redaction serves a clear purpose, such as protecting privacy or complying with regulations.
- Security: Choose a method that provides the level of security you need. For sensitive information, more secure methods like shapes or third-party tools may be preferable.
- Readability: Ensure that the redaction doesn't compromise the document's readability or layout.
By keeping these considerations in mind, you can choose the most appropriate method for your specific needs.
