Frequently Asked Questions

Does this remove the underlying text or just draw a black box?

When you enable 'Forensic Flatten Mode', each page is rasterized after blacking out the text and rebuilt into a fresh PDF with zero underlying text strings or metadata—making it impossible to copy-paste or recover redacted words.
