What is Redact PDF?
Redact PDF permanently censors and removes sensitive personal information, social security numbers, banking details, confidential client names, and trade secrets from PDF documents. Unlike superficial black highlight boxes that can be stripped away in other viewers, this tool permanently deletes the underlying text and vector paths within selected redaction zones, ensuring redacted data is 100% irrecoverable. It allows attorneys, administrators, and corporate users to distribute public documents with complete confidentiality compliance.
