How to Use a PDF Redaction Tool to Protect Sensitive Information
What Is PDF Redaction?
PDF redaction refers to the secure process of deleting confidential or sensitive information from a PDF file so that it cannot be accessed, copied, or restored. Unlike simply hiding text behind a shape or white space, true redaction removes the underlying data permanently. The redacted parts are often shown as blacked-out areas, commonly called PDF blackout text, to indicate that content has been intentionally removed clearly. This practice is especially useful in legal, corporate, and healthcare documents where protecting personal or classified details is essential for maintaining privacy and meeting compliance standards.
