What exactly is required for PDF Accessibility?

An accessible PDF is a document that can be used by anyone regardless of disability or technology barriers.

It can be accessed by the following

  • Screen reader programs like JAWS or NVDA
  • Text-to-speech technology
  • Braille Displays
  • Other Assistive Technology

    Accessible PDFs can be accessed on mobile devices, zoomed in 200% or more, or be navigated via voice or keyboard.

What level of compliance are you going for?

There are different levels of compliance typically categorized by the type of entity. For example, here is a list of different accessibility standards that documents can be made accessible too:

  • Section 508 Standards
  • WCAG 2.1 (A, AA, AAA) Standards
  • PDF / UA
  • HHS Standards

Most organizations strive for the baseline Section 508 standard, but I would encourage all businesses to strive for PDF / UA standards as it is more rigorous.

What do all the standards have in common?

  • Document structure tags: Headings, links, lists, tables, artifacts, figures, form fields, etc.
  • Images have alternate text descriptions
  • Appropriate metadata has been set: Title, author, keywords, subject, language
  • Reading order has been set via tags and the reading order panel
  • Color contrast has been tested

What software do I need to make my PDF Accessibility?

The most important software required to make a PDF accessible is Adobe Acrobat Pro. The free versions of adobe will not allow you to make a PDF accessible.

Optional Software

  • Equidox
  • Commonlook
  • Abbyy Finereader

What are PDF Tags?

Tags are the basis for accessibility within a PDF. Without proper tags, there is no accessibility. Tag elements provide semantic information for screen readers, control the reading order, and other important functions. An important first step is to determine if your PDF has tags.
