Author: Amanda Li Last Modified: 2024-08-14

Redacting sensitive information in Word documents can be a tedious and error-prone task, especially when dealing with large documents. Whether you're a legal professional, a compliance officer, or anyone working with sensitive information, ensuring that private data is thoroughly redacted is crucial.

Kutools for Word offers an efficient and user-friendly solution with its newly introduced Redaction Tool. This tutorial will guide you through using this powerful feature to secure your documents effectively.


Why You Need the Redaction Tool

Redacting text manually in Word can be risky and time-consuming. You might overlook some instances of the text or make mistakes that leave sensitive information exposed. The Redaction Tool in Kutools for Word simplifies this process by allowing you to mark, clear, and apply redactions across your entire document with just a few clicks.


Steps to Redact Sensitive Information in Word

By following these steps, you can efficiently mark and obscure any confidential content, ensuring that your document is safe to share or archive without risking exposure of sensitive data.

Important: The Redaction Tool will add marks to your document. It's highly recommended to create a backup of your original document before proceeding to ensure you have an unaltered version available.


Step 1: Enable the Redaction Tool

On the Kutools tab, click on the Redaction Tool button. And a toolbar will appear.

Step 2: Mark the Text for Redaction
  1. Click the Mark button on the toolbar to activate Mark mode.
  2. Select the text you want to redact.
The tool will automatically identify and mark all instances of this text throughout the document.

  • If you’ve marked something by mistake and want to unmark them, please do as follows:
    1. Click the Clear button to switch to Clear mode.
    2. Select the text you want to unmark.
    The tool will remove the mark from all instances of this text across the document.

    Tip: To quickly remove all marks within a specific paragraph or section, select the area, and all marks within it - and identical text throughout the document - will be cleared.
Step 4: Apply the Redactions

Once you’ve marked all the necessary text, click the Apply button.
