Quick Answer: How to Convert PPT to PDF Without Losing Fonts
To prevent font substitution, you must embed the font file directly into the PowerPoint data before exporting. According to Microsoft Support, this ensures the typeface travels with the document regardless of the viewer’s system. Here is the standard fix for 2025:
- Open your PowerPoint file and go to File > Options.
- Select the Save tab in the left-hand menu.
- Check the box “Embed fonts in the file”.
- Choose “Embed all characters” (best for editing) or “Embed only characters used” (best for file size).
- Save the PPT, then export as PDF.
It is the nightmare scenario for any presenter: you spend hours perfecting a deck with a specific, on-brand typography, only to convert it to PDF and see your elegant geometric sans-serif replaced by a default system font like Arial or Times New Roman. This issue creates a disjointed visual experience and degrades the professional perception of your brand.
In 2025, with remote work making PDF sharing the standard for pitch decks and sales collateral, document fidelity is non-negotiable. Whether you are presenting to stakeholders in London or clients in New York, ensuring what you see on your screen matches what they see on theirs is critical. This guide breaks down exactly how to lock your fonts for a flawless PDF conversion every time.
Why Fonts Disappear During Conversion
Before applying the fix, it helps to understand the technical failure. PDF (Portable Document Format) is designed to be a universal snapshot of a document. However, if the PDF engine cannot access the font file on your local system during the “print” or “save” process—or if the font license forbids embedding—it substitutes the missing data with the closest available match.
According to Adobe technical documentation, font licensing flags (DRM) are the most common culprit. Some fonts are designated as “Non-embeddable” by their creators, meaning PowerPoint is legally blocked from including them in the PDF. Knowing this distinction saves significant troubleshooting time.
Method 1: The Native Embedding Solution (Windows)
For PC users, PowerPoint has a built-in “Embed Fonts” feature that solves 90% of these issues. This forces the font data to live inside the PPTX file, allowing the PDF converter to read it correctly.
Step-by-Step Process:
- Navigate to File > Options > Save.
- Locate “Preserve fidelity when sharing this presentation” at the bottom.
- Check Embed fonts in the file.
- Critical Choice: Select “Embed all characters.” While this increases file size, it ensures that if you edit text later or if the PDF converter needs special glyphs, they are available.
- Click OK, Save the PPT, then go to File > Export > Create PDF/XPS.
Method 2: The “Print as PDF” Workaround (Mac & PC)
Sometimes the “Save As PDF” engine in PowerPoint glitches with complex third-party fonts. A proven workaround used by our design team is the virtual printer driver.
Instead of exporting, pretend you are printing the document on paper:
- Go to File > Print.
- In the Printer dropdown menu, select “Microsoft Print to PDF” (Windows) or use the “PDF” dropdown at the bottom of the print dialog (Mac).
- Click Print.
This process flattens the visual information differently than the export engine, often capturing font shapes that the standard converter misses.
Method 3: The “Outline Text” Technique (The Nuclear Option)
If you are using a strictly licensed font or a complex custom typeface that simply refuses to embed, the only 100% fail-safe method is converting your text into vector shapes. Note: This makes the text uneditable, so always save a backup copy of your presentation first.
At PitchWorx, we use this for high-stakes keynote decks to ensure zero rendering errors.
- Select your text box.
- Cut the text box (Ctrl+X).
- Paste it back as a Picture/SVG (Paste Special > Picture (SVG)).
- Or, use third-party vector tools to outline the text before importing to PPT.
Once the text is a shape (SVG), it is no longer a font. It is an image. The PDF will render it exactly as seen, with zero chance of substitution.
Common Mistakes That Break PDF Fonts
Avoid These 3 Errors:
- Using Cloud-Only Fonts: Adobe Typekit or cloud-synced fonts often exist only in the cache. Download and install the .ttf or .otf file locally before designing.
- Ignoring “Read-Only” Warnings: If PowerPoint warns you that a font cannot be embedded due to licensing, do not ignore it. The PDF will fail. Switch fonts immediately.
- Relying on “Standard” Save: Using the shortcut “Save As > PDF” is less reliable than “Export > Create PDF/XPS” for handling embedded data.
Real-World Scenario: The $10M Pitch Deck Fix
We recently assisted a fintech startup preparing a deck for investors using iPads. Their deck utilized a niche geometric font called “Circular Std.” When they emailed the PDF, the iPad’s PDF viewer reverted every header to Times New Roman because iOS did not support the custom font file embedded in the standard way.
The Fix: We identified the non-standard font licensing issue. Our team converted the header slides into SVG vectors within PowerPoint. This retained the sharpness of the text (unlike a JPEG screenshot) while removing the dependency on the font file. The result was a pixel-perfect PDF that helped them secure their Series A funding.
Pre-Export Checklist for 2025
Before you send that PDF to a client, run through this quick audit:
- ✅ Are all custom fonts installed locally (not just cloud-synced)?
- ✅ Is “Embed fonts in the file” checked in Options?
- ✅ Have you checked the font license for embedding permissions?
- ✅ Did you test the PDF on a device that does not have the fonts installed (like your phone)?
- ✅ Is the PDF size reasonable? (Embedding fonts adds 2–5MB per font family).
Conclusion
Font fidelity is about more than just aesthetics; it is about communication integrity. By following these protocols, you ensure your message lands exactly as you intended, regardless of the device used to view it.

Frequently Asked Questions
Why do my fonts look different in PDF?
This happens because the specific font file used to create the slides is missing from the device viewing the PDF, or it wasn’t properly embedded during the export process. The system substitutes a default font in its place.
Can I embed Google Fonts in PowerPoint PDFs?
Yes, most Google Fonts are open-source (OFL) and allow for full embedding. However, you must download the static .ttf versions to your computer rather than relying on web-based syncing.
Does embedding fonts increase file size?
Yes, significantly. Embedding a full font family (Bold, Italic, Regular) can add 3MB to 10MB to your presentation. To mitigate this, use the “Embed only characters used” option for drafts.
How do I fix fonts that say “Restricted License”?
You cannot legally embed these fonts. You must either purchase a license that allows embedding, choose a different font, or convert the text to a vector image/shape within PowerPoint.
Is PDF/A better for fonts?
PDF/A is an ISO standard designed for long-term archiving. It forces all components, including fonts, to be self-contained. Saving as PDF/A (via Options in the Save dialog) often resolves stubborn font issues.
