Making PDFs Accessible — A Practical Guide for 2026

Why PDF Accessibility Matters

PDFs are used for official documents, contracts, and government forms. When they are inaccessible, people with disabilities cannot participate equally.

Key Accessibility Requirements

Text-Based Content

• PDFs should contain actual text, not images of text
• Scanned PDFs need OCR to add a text layer
• Use proper heading hierarchy (H1, H2, H3)

Reading Order

• Content should flow logically when read by a screen reader
• Multi-column layouts need proper tagging to indicate reading order

Alternative Text

• Images within PDFs need alt text descriptions
• Decorative images should be marked as artifacts

Metadata

• Title, author, and language should be set in document properties
• This helps screen readers announce the document correctly

Color Contrast

• Text must have sufficient contrast against its background
• WCAG requires at least 4.5:1 contrast ratio for normal text

Creating Accessible PDFs

From Word/Google Docs

1. Use heading styles (not just bold text)
2. Add alt text to all images
3. Use real lists, not manual bullet characters
4. Set document language
5. Export as PDF with "Create Tagged PDF" enabled

From HTML

1. Use semantic HTML (headings, lists, tables with headers)
2. Include alt attributes on images
3. Set the lang attribute on the html element
4. The PDF converter will preserve the semantic structure

Testing Accessibility

1. Try selecting all text — if you cannot, it is an image-based PDF
2. Use a screen reader to navigate the document
3. Check metadata properties are filled in
4. Verify reading order matches visual layout
