Defining PDF Accessibility

PDF accessibility involves creating PDF files in a way that ensures people with disabilities can access and understand the content and information within them.

It involves incorporating features and structures that enable people with disabilities to perceive, navigate, and comprehend the content contained within PDF documents. Ensuring PDF Accessibility is important to foster inclusion, comply with legal requirements, and ensure everyone has equal access to information.

What is accessibility?

“Accessibility” means usable by all people, including those with disabilities or who use assistive technology. Accessible documents must be readable by assistive technology, as well as understandable and usable on various technologies and platforms. Tags play an important role in this process because they provide information about elements in the document, such as headings, images, tables, lists, and links. It also helps assistive technology users understand the order and hierarchy of document content. 

Requirements for Ensuring an Accessible PDF

  • Tagging PDF
  • Setting the language of the document or content
  • Setting the correct reading order
  • Marking the appropriate heading structure
  • Highlight tables, whether complex or simple. 
  • Mark numbered, bulleted, or nested lists
  • Providing the image description
  • Marking elements as artifacts

  1. Automatic Tagging:

Implement automatic tagging of elements like headings, tables, figures, and lists. This improves navigation for screen readers and other assistive technologies.

Ensure the proper semantic structure of the PDF document. This allows assistive technologies to understand the relationships between different parts of the content.

Provide alternative text descriptions for all non-text content like images, charts, and graphs. This conveys the information to users who cannot visually perceive the content.

  1. Keyboard Accessibility:

Guarantee that all interactive elements in the PDF are accessible using the keyboard. This enables users who rely on keyboard navigation to interact with the document effectively.

  1. Logical Reading Order:

Maintain a logical reading order for the content. This ensures that assistive technologies present the information in a way that makes sense to the user.

  1. Color Contrast:

Use sufficient color contrast between text and background. This is crucial for users with visual impairments to distinguish the information.

  1. Font Selection:

Select easy-to-read fonts like sans-serif fonts and avoid using overly decorative or small fonts.

  1. Language Support:

Embed language information within the PDF to allow assistive technologies to properly pronounce the text and offer language-specific features.

  1. Document Repair Tools:

Develop and integrate tools within PDF accessibility services that can automatically repair common accessibility issues in existing PDFs.

  1. Accessibility Checkers:

Provide accessibility checkers that identify and flag potential accessibility barriers within the PDF document. This allows creators to address these issues before sharing the document.
