What is PDF redaction?

PDF redaction is the process of permanently removing or obscuring sensitive information from a PDF document. Unlike simply adding a black rectangle, true redaction removes the underlying text data so it cannot be recovered.

Can redacted information be recovered?

This tool removes original text data from the PDF content stream after redaction, leaving only black rectangles. Redacted text cannot be recovered by copying, pasting, or searching, ensuring information security.
