Is it true that a PDF document must be untagged for screen reader users to access it?

A PDF document should be tagged to ensure that screen reader users can effectively access and navigate its content. Tagged PDFs contain structural elements such as headings, lists, and tables that provide a clear organization of the information. This tagging allows assistive technologies, like screen readers, to interpret the document in a manner that is meaningful to users with visual impairments, facilitating smoother navigation and comprehension.

On the other hand, untagged PDFs present significant barriers for these users. Without tags, a screen reader may read the content without context, leading to a confusing experience where users struggle to discern the layout and relationships between different pieces of information. Thus, tagging is essential for enhancing accessibility and ensuring that all users, regardless of ability, have equal access to the content within a PDF document.
