PDF extraction remains challenging because the format was designed for print fidelity, not machine readability. Created in 1991 to solve cross-platform document consistency, PDFs treat content as positioned text boxes rather than structured data. Modern AI tools now require complex multi-layer processing (layout analysis, OCR, vision models) to extract meaningful information from PDFs. While Tagged PDF and other standards attempt to add structure, adoption remains limited. The solution involves choosing semantic formats for new content and supporting open standards that preserve both visual fidelity and machine readability.
