Redact PDF Text
Draw a black box over part of a page to visually hide it.
Important — this is visual redaction only
This draws an opaque black box over the selected area — it does not remove or search-scrub the underlying text layer. Someone could still copy-paste or extract the "hidden" text from the PDF's data. For genuinely sensitive information, use dedicated redaction software that strips the underlying content, not just a visual overlay.
