What is pdf accessibility testing?

PDF accessibility testing is the process of evaluating PDF documents to ensure they can be accessed, read, and navigated by people with disabilities, including those who use screen readers or other assistive technologies. This involves checking that the document includes proper tags, alternative text for images, logical reading order, and adequate color contrast, among other criteria. The goal is to make sure the PDF complies with accessibility standards such as WCAG (Web Content Accessibility Guidelines) and Section 508. Proper accessibility testing helps organizations provide equal access to information for all users.
