Sighted users perceive headings using visual cues such as large fonts, boldface, and colored text. This information is often unavailable to people with visual impairments or who require assistive technology. Consequently, if headings are not identified in the formatting of the presentation, then assistive technology cannot represent the document’s sections and subsections to the reader.
PowerPoint itself has a limited concept of headings; PDF is far more capable. Using CommonLook Office to add structure to your presentation when output to PDF adds tremendous value in terms of making even the longest presentations highly navigable.
In PowerPoint, headings are controlled loosely by the content layout. Slide layouts with a title block default to using the Title as an H1 heading, which is generally not ideal. In most cases it’s preferred to use only one H1 heading in any given document, so it’s advisable to assign your headings accordingly, with major section titles assigned to H2 and subsections to H3.
To manage heading levels in output PDF files. use the Style Mapping Checkpoint in CommonLook Office.
CommonLook Office allows for complete control of headings and other objects in its output from PowerPoint to PDF.
