## Inside a PDF Document
Unlike images, PDFs are composed of structured object streams containing text drawing operators (`Tj`, `TJ`), coordinate transformations (`cm`), and graphics states.
Superficial redaction tools draw black boxes on top of content streams, leaving underlying text accessible to copy-paste. PrivacyFold's destructive redactor excises the text operators from the content stream itself.
