PDF is a visual format that stores instructions for drawing glyphs on a page, with support for Tagged PDF to mark headings and paragraphs. Most PDFs are untagged due to limitations in tools like LaTeX and Chrome's print-to-PDF, resulting in text extractors reading draw commands sequentially without structural context.
