Use the Remove Hidden Information feature to find and remove hidden content from a PDF. For example, if you
created the PDF, the document metadata normally lists your name as the author. You may also want to remove content
that can inadvertently change and modify the document’s appearance. JavaScript, actions, and form fields are types of
content that are subject to change.

Redaction is the process of permanently removing visible text and graphics from a document. You use the Redact tools

can leave the area blank. You can specify custom text or redaction codes to appear over the redaction marks.
Note: If you want to locate and remove specific words, characters, or phrases, use the Find Text tool instead.
