1. Why Accessible PDFs Matter
Accessible PDFs ensure that all users, including those using assistive technologies like screen readers, can navigate and understand the document content equally. They are often a legal requirement and promote inclusivity.
2. General Rules for PDF Accessibility
- Use proper headings to structure content logically.
- Provide alternative text for meaningful images.
- Ensure reading order is logical and matches the visual order.
- Tag all content properly (headings, paragraphs, lists, tables).
- Use accessible fonts and maintain sufficient color contrast.
- Ensure links are descriptive (avoid "click here").
- Use tables for data only, not for layout.
3. Creating Accessible PDFs from Microsoft Word
- Use Word's built-in Styles for headings and lists.
- Set alternative text for images via the "Alt Text" pane.
- Use built-in tools for tables with simple structures and headings.
- Run Word's Accessibility Checker before exporting.
- Save As PDF using "Best for electronic distribution and accessibility" option.
4. Creating Accessible PDFs from Microsoft Excel and PowerPoint
- In Excel, define table headers and avoid merging cells unnecessarily.
- Use simple tables and clear tab order.
- In PowerPoint, use built-in layouts rather than text boxes for content.
- Assign alt text to images and charts in both Excel and PowerPoint.
- Export using accessible PDF options in Save As.
5. Converting Google Docs to Accessible PDF
- Use Styles (Headings 1, 2, etc.) for document structure.
- Add alt text to images (Right-click → Alt Text).
- Download as PDF via "File" → "Download" → "PDF Document".
6. Converting HTML to Accessible PDF
- Ensure HTML uses semantic tags correctly (h1-h6, ul, ol, etc.).
- Use "Print to PDF" options carefully; ensure structure is maintained.
- Use specialized software if needed to preserve semantics.
7. Creating Accessible PDFs Using Adobe Acrobat
- Use "Make Accessible" wizard to auto-tag content.
- Manually inspect and fix tagging issues (especially tables and forms).
- Set document properties (Title, Language, etc.).
- Run "Accessibility Checker" in Acrobat Pro.
8. Creating PDFs Using Web APIs
- Use APIs that support tagging (e.g., Adobe PDF Services API).
- Ensure the API documentation mentions support for accessibility features.
- Post-process PDFs with tools like Acrobat if needed for manual adjustments.
