How to Redact a PDF Before Sharing
Before sharing a PDF, check whether it includes account numbers, addresses, phone numbers, signatures, or internal notes. Masking visible information is a simple first step for safer sharing.
Find every sensitive area
Scan every page for personal details, financial data, signatures, QR codes, and hidden notes. Sensitive information is often repeated in headers, footers, and attachments.
Use masks for visible content
Add solid masks over visible text or image areas that should not be shared. Review at normal zoom and high zoom before downloading the edited PDF.
Use the right tool for legal redaction
Visual masking is useful for many everyday sharing workflows, but regulated legal redaction may require a specialized certified tool and a review process.
