The PAC PDF Accessibility Checker is a free tool designed to evaluate whether a PDF document meets accessibility standards, such as PDF/UA, ensuring it can be properly used with assistive technologies like screen readers. It analyzes elements such as document tags, reading order, alternative text for images, and overall structure, then provides a detailed report highlighting errors, warnings, and areas that need manual review. While PAC does not fix accessibility issues, it plays a key role in identifying problems so they can be corrected using tools like Adobe Acrobat Pro.
