How to Redact a Word Document

To redact a Word document permanently, replace each piece of sensitive text with [REDACTED] using Find and Replace, run Document Inspector to remove hidden metadata, and save as a new file. Word does not have a dedicated Redact tool, so do not rely on highlighting text in black or using a colored shape, the original text stays in the file and is recoverable.

Why black highlighting in Word is not real redaction

Highlighting text black is the most common mistake. The text stays in the document; a reader can select it, copy it, change the highlight color back to none, or open the .docx as a ZIP archive and read the underlying XML. The same applies to using a black shape from Insert > Shapes. Word offers no native redaction tool that matches what Adobe Acrobat Pro does for PDFs, so the workflow has to be different.

The right Word redaction workflow

1. Open the document and press Ctrl+H (Cmd+H on Mac) for Find and Replace.
2. For each piece of sensitive text, type it in "Find what" and [REDACTED] in "Replace with". Click Replace All.
3. Repeat for every piece of sensitive content. This is tedious but it actually deletes the text.
4. File > Info > Check for Issues > Inspect Document. Select all checkboxes. Click Inspect, then Remove All for every category that finds results (comments, tracked changes, document properties, hidden text).
5. Save As a new file with a clear name like contract_redacted.docx. Never overwrite the original.

When to convert to PDF instead

For documents going to court or external counsel, convert to PDF after redaction and re-redact in a tool that handles PDF content streams. Word's [REDACTED] placeholder approach is acceptable for internal review but does not provide the audit trail or visual block that legal filings expect.
