How PDFly converts PowerPoint to PDF
PDFly uses a combination of open-source libraries to extract and convert your presentation content:
- File extraction: Using JSZip, the tool reads the .pptx file (which is actually a ZIP archive) and extracts the slide XML files.
- Text extraction: The slide XML is parsed to extract all text content — titles, bullet points, and body text.
- PDF generation: Using pdf-lib, each slide's text is rendered on a separate PDF page with a clean, readable layout.
- Slide count: Each slide becomes one PDF page, preserving the presentation structure.
What's preserved and what's not
Preserved:
- Slide titles and text content
- Bullet points and lists
- Paragraph structure and order
- Slide numbering
Not preserved:
- Images and graphics
- Custom fonts and colors
- Animations and transitions
- Audio and video files
- Complex slide layouts and design elements
- SmartArt and charts
Troubleshooting
- "No slides found" error: The file may not be a valid .pptx file. Try opening it in PowerPoint and saving it as a new .pptx file.
- The PDF is missing some text: Some PowerPoint text (especially in text boxes) may not be extracted. Check the slide layout in the original file.
- The PDF looks different from the presentation: This tool preserves text but not visual design. For pixel-perfect conversion, use PowerPoint's native export.
- The conversion is slow: Large presentations with many slides or complex text take longer to process. Be patient — it's running entirely in your browser.
