How to Redact a PDF — Permanently Remove Sensitive Information | PDF AI Work Blog
PDF AI Work Team·
Redaction is NOT the same as drawing a black box over text. The Redact PDF tool permanently deletes content from the PDF's data stream — once redacted, no one can recover the information.
Why Proper Redaction Matters
Drawing black rectangles or changing text color to white leaves the underlying content in the PDF file. Anyone can select, copy, or remove the overlay to reveal it. True redaction deletes the actual text and image data from the document.
- Open Redact PDF
- Upload your PDF
- Mark areas to redact using the rectangle tool
- Click Apply Redaction — content is permanently removed
- Download the sanitized PDF
Always verify: after redacting, try to select or copy the redacted area. If you can, the redaction didn't work. Also: Protect PDF, PDF Metadata to clean hidden data.
