Why Fonts Do Not Convert from PowerPoint to PDF and How to Fix It
Question details
Specific custom fonts used in a presentation are omitted or replaced by default fonts when the file is saved or exported as a PDF.
- Product
- PowerPoint
- Device & OS
- not provided
- Scenario
- Exporting or saving a slide deck to a PDF format for sharing, distribution, or printing.
- Observed behavior
- The resulting PDF document fails to display the original fonts used in the presentation, causing broken layouts, misaligned text, or an unintended design appearance.
Verify the exact name of the missing font and check if it was downloaded from a third-party source, as custom fonts often carry strict licensing rules that restrict document embedding.
Check Font Embedding Permissions and Replace Restricted Fonts
Identify if the problematic font has a restrictive license preventing PDF embedding, and replace it with a web-safe or fully licensable alternative.
Many third-party fonts have built-in digital rights management (DRM) or licensing flags that prevent them from being embedded into exported documents like PDFs. If PowerPoint detects this restriction, it will block the embedding process and substitute the font automatically during conversion.
Open your original PowerPoint presentation and navigate to 'File' > 'Options'.
Select the 'Save' tab from the left sidebar. Scroll down to the 'Preserve fidelity when sharing this presentation' section and check the box for 'Embed fonts in the file'.
Attempt to save the file. If you receive a warning prompt stating 'Some of your fonts cannot be saved with the presentation', note down the specific font names listed.
Go back to your slides, highlight the text using the restricted font, and change it to a universally supported standard font (such as Arial, Calibri, or Open Sans).
Once all restricted fonts are replaced, go to 'File' > 'Export' > 'Create PDF/XPS Document' to successfully generate your PDF with intact formatting.
Use the Print to PDF Feature as a Workaround
Bypass the native PDF export tool by using the system's virtual PDF printer to force the visual representation of the font onto the document.
Use WPS Presentation for Flawless PDF Conversion
WPS Office offers a robust Presentation tool that easily manages font embedding and high-quality PDF exports. It preserves your original formatting effortlessly, giving you an excellent, free alternative for handling everyday document tasks.

Frequently Asked Questions
How do I know if a font allows embedding in PDFs?
You can check a font's embeddability properties in your operating system. On Windows, go to Settings > Personalization > Fonts, click on the specific font, and look for the 'Font embeddability' status. If it says 'Restricted' or 'No embedding', it cannot be packaged into a PDF.
Why do the fonts work perfectly on my screen but not in the converted PDF?
When you view the presentation on your own computer, the software loads the font directly from your local system folder. When exporting to PDF, the actual font file must be packaged (embedded) inside the PDF so others can see it. Licensing restrictions can block this packaging process, causing the failure during export.
Can I embed custom fonts using PowerPoint for Mac?
Yes, recent versions of PowerPoint for Mac support font embedding. You can enable it by going to PowerPoint > Preferences > Save, and checking 'Embed fonts in the file'. However, if a font's license restricts embedding, the conversion will still fail, exactly as it does on Windows.
What happens to the PDF if I simply ignore the embedding warning?
If restricted fonts are not embedded, the PDF viewer (like Adobe Acrobat or a web browser) will attempt to substitute the missing font with a default system font. This substitution often drastically alters text sizing, line breaks, and the overall design of your presentation.
