Auto-Tag PDF
Enhance PDF accessibility compliance with AI-powered auto-tagging
Why Tagged PDFs Matter for Accessibility
A tagged PDF contains a hidden structure – a tag tree – that defines elements like headings, paragraphs, lists, tables, and images.
This ensures compliance with WCAG and PDF/UA standards, making documents accessible for screen readers and assistive technologies.
