Table of Contents
The Two Audiences Framework
Every PDF serves visual readers and assistive technology. If structure is missing, one audience is effectively excluded.
Accessibility is not cosmetic. It is structural quality that improves usability, compliance posture, and distribution reach.
Core Accessibility Components
Accessible PDFs need semantic tags, meaningful heading hierarchy, alt text for informative images, and correct reading order.
Color contrast and descriptive link text also matter for non-screen-reader accessibility.
- Set language and document title.
- Use real text instead of image-only text blocks.
- Define table headers clearly.
Build-First, Retrofit-Later Rule
Accessibility is cheaper when authored in source documents first. Convert with Word to PDF from properly structured inputs.
If legacy files are poor, recover structure through PDF to Word, improve semantics, then export again.
Operational Checklist
Run a repeatable QA pass for heading order, alt text coverage, table semantics, and navigation quality on multi-page files.
