How to Redact PDF – Full Guide for Extracting Sensitive Data from PDFs
Introduction
People often use PDF to send contracts, reports, invoices, legal documents, medical records, and information about their businesses to others. PDFs are great for consistency and compatibility, but they usually have information that is confidential to those who need it to be private. The sharing of personal information, financial information, client information, trade secrets, and internal notes can be a huge privacy and security problem if not properly reviewed.
That’s where PDF Redaction tools for Redacting PDFs come in handy. Redaction refers to the process of permanently removing sensitive information from a document before distribution, ensuring no one can reconstruct the data. Proper PDF redaction deletes the underlying code entirely so users cannot recover it, unlike amateur methods that merely cover text with a black box.
