PDF is a format for representing documents while preserving their layout. It can include text, images, links, forms and other elements, depending on how the file was created
What it means, how it is used and where it comes up, with its related concepts.
What it is and how it works
Not all PDFs embed the same fonts or meet archival, printing or accessibility requirements. The PDF/A, PDF/X and PDF/UA variants serve specific purposes. A document that looks good can still be difficult to read with assistive technologies; the content needs appropriate structure, order and alternatives.
