Announcing no-cost access to PDF’s accessibility standards

August 2024 by PDF Association staff

Starting today, all PDF users can begin to leverage ISO-standardized accessibility requirements for PDF files:

  • End users who need assistive technology in order to navigate and read digital documents can use these standards to foster improved products and services.
  • Organizations can use these standards to set goals for the documents they create, ingest or manage.
  • Document remediators can use these standards in performing professional services related to ensuring PDF files are accessible.
  • Software developers can these standards as guidance in developing software to create and process tagged PDF.

Thanks to these leading PDF accessibility companies

“Today, the PDF Association is delighted to announce no-cost access to the ISO standards that define the gold standard for accessible PDF files” said Duff Johnson, PDF Association CEO. “We are grateful to the PDF Association’s member sponsors – Allyant, Axes4, CDP Communications and TargetStream Technologies – who have stepped up to make this possible.”
