July 11, 2013: After eight years of effort, the International Organization for Standardization published ISO standard 14289-1, known as PDF/UA (Universal Accessibility). PDF/UA represents the definitive, worldwide standard for PDF accessibility.
PDF/UA offers the promise of empowering all users, including those who rely on assistive technology, to enjoy a reliable, high-quality reading experience.
The benefits of PDF/UA will extend beyond people with disabilities. With support for PDF/UA, reader software will be able to reliably reflow text onto small screens, provide powerful navigation options, transform text appearance, improve search engine functionality, aid in the selection and copying of text, and more.
