What is Redact PDF?
Redact PDF permanently blacks out sensitive areas of a PDF. After drawing the boxes, each page is rebuilt as an image, so the text underneath is genuinely gone and cannot be copied or extracted.
Common uses
- Hiding personal details. Black out account numbers, addresses or ID numbers.
- Legal and compliance. Remove confidential content before disclosure.
- Sharing excerpts. Publish a document with sensitive passages removed.
- HR and finance. Hide salaries or names in shared records.

- Run OCR PDF afterwards if you need searchable text in the safe parts.
