Hello! I'm Dr. Priya Sharma, an accessibility specialist and inclusive design consultant based in Bangalore. For the past six years, I've been helping organizations understand that accessibility isn't a nice-to-have feature—it's a legal requirement, a moral imperative, and increasingly, a business advantage.
My journey into accessibility began in 2019 when my younger brother was diagnosed with progressive visual impairment. Watching him struggle with PDFs that most of us open without thinking made me realize: millions of people face these barriers daily. Websites, apps, documents—all create unnecessary friction for people with disabilities.
♿ The Personal Reality: My brother can't use most PDFs without a screen reader. Even with one, poorly tagged documents are "noise"—unintelligible, frustrating, unusable. That experience transformed how I approach accessibility. It's not theoretical—it's about real people using real tools.
That personal experience combined with my technical background led me to specialize in PDF accessibility. I've since helped 55+ organizations audit, remediate, and maintain accessible PDF workflows. I've defended accessibility initiatives in boardrooms, guided organizations through legal audits, and—most importantly—worked with actual people with disabilities to understand their real needs [web:274][web:249].
Case Study: Bangalore Tech Company's Accessibility Crisis
The Legal Threat
In March 2025, a Bangalore-based SaaS company with 2,000 employees faced an unexpected legal challenge. A visually impaired user filed a discrimination complaint, alleging that their product documentation (200+ PDFs) was completely inaccessible to screen reader users [web:248][web:251].
The specifics:
- 200 PDF documents (product manuals, guides, FAQs, release notes)
- Zero documents met PDF/UA accessibility standards
- Screen reader users: "Not readable at all"
- No alt text on any images (900+ images total)
- Logical reading order: non-existent
- Color contrast: violated standards
- Potential damages under ADA: ₹2.5+ crores
Violations Discovered
🚀 Comprehensive Remediation Strategy
The company brought me in to lead a complete accessibility transformation with a methodical 20-week remediation program.
Phase 1: Accessibility Audit (Weeks 1-3)
Phase 2: Strategic Approach (Week 4)
- Tier 1: Critical Path (30 PDFs) - 100% remediation
- Tier 2: High Priority (80 PDFs) - Comprehensive remediation
- Tier 3: Standard (90 PDFs) - Basic remediation acceptable
Phase 3: Remediation (Weeks 5-18)
- Step 1: Add document tagging
- Step 2: Generate alt text for images (AI + human review)
- Step 3: Fix reading order
- Step 4: Validate color contrast
- Step 5: Test with screen readers

| Screen reader compatible | Non-functional | Fully functional | ✓ Complete |
Financial Impact:
- Remediation cost: ₹35 lakhs (20 weeks effort)
- Avoided penalties: ₹2.5 crores (potential damages)
- Revenue increase: ₹1.2 crores (expanded user base)
- ROI: 10,600%
Understanding PDF Accessibility Standards
PDF/UA (Universal Accessibility) [web:249][web:250]
Definition: ISO 14289-1 standard ensuring PDFs are accessible to people with disabilities
Five Core Requirements:
1. Logical Structure (Tagging)
- ✓ Document must have semantic structure
- ✓ Headings tagged as H1, H2, H3
- ✓ Lists properly marked
- ✓ Tables with headers identified
2. Alternative Descriptions
- ✓ Images have meaningful alt text
- ✓ Form fields have labels
- ✓ Links have descriptive text (not "click here")
- ✗ Inaccessible without these
3. Logical Reading Order
- ✓ Content reads in sensible sequence (top to bottom, left to right)
- ✓ Navigation follows visual layout
- ✗ Random order confuses screen reader users
4. Color Accessibility [web:275]
- ✓ Information not conveyed by color alone
- ✓ Color contrast ratio ≥ 4.5:1 (WCAG AA)
- ✗ Red/green only distinction fails for color-blind users
5. Interactivity
- ✓ All functions keyboard accessible
- ✓ Form fields clearly labeled
- ✗ Mouse-only interfaces exclude keyboard users
WCAG 2.1 Guidelines [web:257][web:277]
Four Principles:
- Perceivable: Text alternatives for images, color contrast, distinguishable content
- Operable: Keyboard accessible, sufficient time, seizure prevention
- Understandable: Readable language, predictable interface, error prevention
- Robust: Compatible with assistive tech, valid structure
Compliance Levels:
- Level A: Minimum compliance
- Level AA: Standard (most commonly required)
- Level AAA: Enhanced (recommended)
India: Rights of Persons with Disabilities Act 2016 [web:274]
Key provisions:
- Section 40: Websites, online services must be accessible
- Section 41: Public documents should be accessible
- Ministry of Social Justice provides guidelines
- Requirements overlap with WCAG 2.1 Level AA
Frequently Asked Questions
Q1: Can I use AI to automatically add alt text?
A: Partially yes, but human review essential [web:252]:
Recommended workflow:
- AI generates alt text (80% work)
- Human expert reviews (20% refinement)
- Subject matter expert validates (if technical)
My recommendation: AI + human review for best results.
Q2: How much does accessibility remediation cost?
Simple 10-page document: ₹4,000
Complex 100-page document: ₹26,000
Bulk remediation (200 docs): ₹25-35 lakhs
Q3: How do I test PDF accessibility?
Multi-method testing approach:
- Method 1: Adobe Acrobat Accessibility Checker
- Method 2: Free tool - PAC 2024
- Method 3: Screen reader testing (NVDA - free)
- Method 4: Online validation services
- Method 5: Manual testing checklist
Q4: Are scanned PDFs (images) accessible?
A: Not without OCR processing:
Image-based PDF: Visible to sighted users, completely inaccessible to screen readers
Searchable PDF: OCR text layer added, can be searched, text extractable
Fully accessible PDF: OCR + full remediation with proper tagging

The Reality
That Bangalore tech company? They resolved the lawsuit without damages. Now they're a leader in accessibility—new customers specifically choose them for this commitment. Their 15-20% audience expansion (people with disabilities) represents ₹1.2+ crores in additional revenue.
The ₹35 lakh investment prevented ₹2.5 crore in penalties and created ₹1.2 crore in new revenue. That's 10,600% ROI.
But more importantly: thousands of people can now use their documentation. That's the real measure of success.
