How can one improve the accessibility of PDFs?

Improving the accessibility of PDFs is crucial for ensuring that all users, including those with disabilities, can access and understand the content. The option that enhances accessibility most effectively is using tagged PDF formats and ensuring proper reading order.

Tagged PDFs contain structural information that helps screen readers interpret the content correctly. This includes identifying headings, paragraphs, lists, and other elements which assist users who rely on assistive technologies. Proper reading order ensures that as the screen reader navigates through the document, it follows the intended sequence, making it coherent and easier to comprehend.

In contrast, removing all images and media would likely degrade the user experience by stripping away visual information that may be essential, particularly for context. Compressing the file size could improve downloading times but does not directly enhance accessibility, as it addresses performance rather than usability for individuals with disabilities. Similarly, using color-coded text for emphasis may pose challenges for users with color blindness or visual impairments, as they may not perceive the information as intended. Therefore, tagging and ensuring a logical structure is the most effective way to improve PDF accessibility.
