Enhance PDF Accessibility with AI-Powered Auto-Tagging Using PDFix

Why Tagged PDFs Matter for Accessibility
A tagged PDF contains a hidden structure (tag tree) that defines elements like headings, lists, tables, and alt text for images. This ensures compliance with WCAG and PDF/UA standards, making documents accessible for screen readers and assistive technologies.
