Why Do Black Highlighter Boxes Fail to Redact Confidential PDF Text?

Drawing black rectangles over text in standard PDF readers only places a cosmetic visual layer on top, leaving underlying text and vector streams fully extractable via copy-paste. NoPayWall executes forensic redaction: it removes the underlying text glyphs and font stream objects completely from the PDF binary data before drawing the blackout region, ensuring zero metadata or text recovery by automated forensic scanners.
