Heading text helps people scan content and are typically represented by large and bold text . Changing the style of the text will not tell assistive technology users the text is a heading. If your PDF contains only paragraph tags (<P>) in the Tags Tree, update the tags of heading text to heading tags (<H1>, <H2>, etc.).

Unlike in HTML, the PDF standard allows for multiple H1 headings in the same document. However, the nested heading hierarchy should be maintained.
