What is PDF?
PDF is a fixed-layout document: it records what is drawn where on a page rather than paragraph structure, so the layout is identical everywhere and can never reflow.
About the format
PDF is Adobe's fixed-layout document format. It records what to draw at which coordinate on a page rather than which paragraph a sentence belongs to. The layout is therefore identical everywhere, which suits contracts, papers and scans. The cost is that PDF is inherently hostile to reflow: line breaks are usually visual, extracted text often carries hard returns and scrambled column order, and scanned PDFs contain images only, with no text layer at all.
