Overview ​

Redaction is the process of removing visible text or images from a document, often permanently deleting or overwriting sensitive information and completely removing it from the PDF metadata. Revised content is often replaced with black bars or other visually prominent markings to indicate that the information has been redacted.

Redaction is commonly employed to safeguard privacy, comply with legal requirements, or ensure that sensitive content is not inadvertently disclosed. This process facilitates secure distribution to audiences such as courts, patent and government agencies, media, clients, suppliers, or any other restricted-access entities.
