PDF Accessibility Remediation & WCAG Compliance
Automate PDF tagging, alt text generation, and WCAG 2.1 / Section 508 compliance at scale.
Solution Overview
Organisations in publishing, government, healthcare, legal, and education must ensure their PDFs are accessible to users with disabilities — compliant with WCAG 2.1, PDF/UA, and Section 508 standards. Cray automates the bulk of PDF remediation: document structure tagging, reading order correction, alt text generation for images, table tagging, and form field accessibility — reducing what takes hours per document to minutes.
The Manual Process Problem
Accessibility specialists manually open each PDF in Adobe Acrobat Pro, add document structure tags, define reading order, write alt text for every image, tag tables with header rows, and mark decorative elements — averaging 2–8 hours per document depending on complexity. For organisations with thousands of documents, this backlog is unmanageable.
Cray's Automation Approach
AI-powered document structure analysis detects headings, paragraphs, lists, tables, and figures automatically. NLP-based alt text generation describes images contextually. Reading order is inferred from layout analysis. Automated compliance checking runs against WCAG 2.1 Level AA, PDF/UA, and Section 508 standards. A human accessibility expert reviews and approves only flagged edge cases — achieving 80%+ automation coverage.
