What is PDF Accessibility

PDF Accessibility (typically called PDF/UA which stands for “User Accessibility” or ADA stands for “Americans with Disabilities Act”)means the PDF document contains features that make it more accessible for people with disabilities, such as mobility impairments, blindness, and low vision.

PDF/UA

PDF/UA is the informal name for ISO 14289, the International Standard for accessible PDF technology. A technical specification intended for developers implementing PDF writing and processing software, PDF/UA provides definitive terms and requirements for accessibility in PDF documents and applications. For those equipped with appropriate software, conformance with PDF/UA ensures accessibility for people with disabilities who use assistive technology such as screen readers, screen magnifiers, joysticks and other technologies to navigate and read electronic content.
