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 Pane, update the tags of heading text to heading tags (<H1>, <H2>, etc.).
Select the tag you wish to change to a heading. The text in the document should have a blue box around it. Right click (Windows) or command click (Mac OS) the tag and choose Properties from the list of options.
In the Object Properties dialogue box, select the Type drop down and choose the new heading level from the list of options. You can also type "Heading Level 1" into the Type field, but be sure to use the correct name with capitalization. The Type field is case sensitive.
Another way to change the Type of tag is to change it in the Tags Pane. Remember the tag code is case sensitive.
Double click the tag you want to change. An edit box will appear in place of the tag.
Type the corrected tag code with < and > signs surrounding and press the Enter Key.
