How to Redact Sensitive Information and Black Out Text in PDF Permanently
Drawing a black highlight over text in basic viewers does NOT protect your data—anyone can copy and paste the underlying text right through the box! True redaction requires permanently deleting the underlying vector text and glyphs from the PDF file so it can never be recovered.

Perguntas frequentes
Can someone highlight or copy text underneath the black boxes?
When flattened using iEditPDF, the text characters beneath the redaction are permanently discarded from the PDF stream, making text extraction impossible.
Why is drawing a highlighter box in preview apps unsafe?
Most basic viewers merely overlay a semi-transparent color on top of live text. Anyone can press Ctrl+A and Ctrl+C to copy all the 'hidden' text in seconds.
Is this redaction safe for legal and confidential filings?
Yes, permanent content stripping removes hidden text layers, metadata, and visual data entirely, making it safe for confidential and official e-filing.
