Exporting to PDF
What it is
Exporting to PDF converts your PowerPoint presentation into a Portable Document Format file that can be viewed on any device without PowerPoint software. PDF is commonly used for sharing final versions of presentations that don't need to be edited.
When done correctly, PDF export preserves accessibility features like alt text, reading order, and structure. However, some features like animations and interactive elements don't transfer to PDF format.
Why it matters
Accessible PDF export is important because:
- Universal access: PDFs work on almost any device without special software
- Preserves content: Fixed layout ensures consistent appearance across platforms
- Archival: Standard format for long-term document storage
- Accessibility: When tagged properly, PDFs work with screen readers and assistive technologies
- File sharing: Widely accepted format for professional document exchange
However, if accessibility features aren't preserved during export, the PDF becomes a barrier for users with disabilities. Proper export settings and verification are essential.
How to export to accessible PDF
PDF export is a common way to share presentations, but maintaining accessibility during export requires specific steps and settings.
PowerPoint to PDF export process
Step-by-step accessible PDF export
- Go to File → Save As
- Choose PDF (*.pdf) as the file type
- Click Options button
- Check "Document structure tags for accessibility"
- Ensure "Include hidden slides" is unchecked (unless needed)
- Select "Optimize for: Minimum size" for web sharing
- Click OK and then Save
Advanced export options
- Range selection: Export only necessary slides
- Handout formats: Consider 2-4 slides per page for readability
- Notes inclusion: Export speaker notes for comprehensive content
- Quality settings: Balance file size with image quality
What transfers to PDF
Accessibility features that transfer well
- Alt text: Image descriptions are preserved
- Text content: All readable text becomes selectable
- Basic structure: Slide titles become headings
- Reading order: Generally follows PowerPoint's reading order
Features that may not transfer
- Animations: Motion effects are lost
- Interactive elements: Buttons and links may not work
- Complex layouts: Reading order may be disrupted
- Audio/video: Multimedia content is not included
PDF export quality considerations
Format comparison table
| Format | Accessibility Retention | Best Use Cases | Considerations |
|---|---|---|---|
| PPTX (Native) | Excellent | Collaborative editing, full feature access | Requires PowerPoint or compatible software |
| Tagged PDF | Good | Read-only sharing, archival | May need post-export accessibility fixes |
| HTML/Web | Variable | Web publishing, broad accessibility | Depends on export method and platform |
| Images (JPG/PNG) | Poor | Visual previews only | Avoid for primary sharing; supplement only |
⚠️ Common PDF export issues
- Reading order problems: Complex layouts may export with illogical order
- Missing alt text: Some images may lose descriptions
- Poor heading structure: Slide titles may not be properly tagged
- Table structure loss: Tables may become unstructured text
Always test exported PDFs with accessibility tools.
PDF verification and testing
After exporting to PDF, it's crucial to verify that accessibility features have been preserved and the document works well with assistive technologies.
Automated accessibility testing
Using Adobe Acrobat accessibility checker
- Open PDF in Adobe Acrobat Pro
- Go to Tools → Accessibility → Full Check
- Review the accessibility report
- Fix identified issues using Acrobat's remediation tools
- Re-run check to verify fixes

Manual testing procedures
Screen reader testing
- Navigation test: Can users jump between headings?
- Reading order test: Does content flow logically?
- Alt text test: Are image descriptions read correctly?
- Table test: Can users navigate table structure?
Visual accessibility testing
- Zoom test: Does content remain readable at 200% zoom?
- Contrast test: Is text readable against backgrounds?
- Color test: Does content work in high contrast mode?
- Print test: Is the PDF readable when printed in black and white?
Common remediation tasks
Fixing reading order
- Open Order panel in Adobe Acrobat
- Review the content structure tree
- Drag elements to correct order
- Test with screen reader
Adding missing alt text
- Right-click on image in PDF
- Select Properties
- Go to General tab
- Add text in Alternate Text field
Improving heading structure
- Access Tags panel
- Find slide titles in structure tree
- Change tag type to appropriate heading level (H1, H2, etc.)
- Verify heading hierarchy makes sense
