Why This Matters
PDF accessibility is critical for government, education, and legal documents. Untagged PDFs read as a wall of text to screen readers. WCAG and PDF/UA require proper tagging, document language, title metadata, and navigable structure. The DOJ ADA Title II rule references PDF/UA-1 as the conformance target for digital documents.
