Why Fonts Change When Converting Word to PDF & How to Fix It
Question details
The user experiences unexpected font substitutions when converting a Word document to a PDF file, specifically with premium fonts.

- Product
- Word to PDF Converter
- Device & OS
- not provided
- Scenario
- Exporting or saving a completed Word document containing custom fonts into a PDF format for sharing or printing.
- Observed behavior
- Custom fonts such as Luminari and Lucida Blackletter are not retained in the output PDF and are automatically replaced with standard default fonts.
Verify the exact names of the fonts that are altering during the conversion process and confirm they are fully installed on your current operating system.
Check Font Licensing and Embedding Permissions
Determine if the font manufacturer restricts embedding in digital documents, which is the primary cause of fonts being substituted during PDF conversion.
Many premium fonts, including Luminari and Lucida Blackletter, have strict licensing rules enforced by foundries such as Linotype or Monotype. If a font's license explicitly restricts embedding, standard PDF converters will bypass it and substitute a default system font.
To resolve this, you must review the font's End User License Agreement (EULA) and potentially acquire a license that permits digital redistribution.
Open your original Word document, highlight the text that changes during conversion, and note the exact font name displayed in the Home tab.
Navigate to your system's Font settings (e.g., the Fonts Control Panel in Windows) and review the 'Font embeddability' property for the specific font.
Visit the font foundry's official website (such as Microsoft Typography or Linotype) and search for the font's specific licensing and redistribution details.
If the font is restricted, you must either purchase an extended license that allows embedding, or change the document's font to an unrestricted, open-source alternative before converting to PDF.

Enable Font Embedding within Document Settings
Configure your word processor to save the font data directly inside the document file before initiating the PDF conversion.
Convert Word to PDF Accurately with WPS Office
WPS Office features a powerful, built-in PDF converter that accurately preserves your original document layouts and smoothly handles standard font embedding, ensuring your files look exactly as intended when shared.
- 1. Open your document: Launch WPS Writer and open the document containing the fonts you wish to preserve.
- 2. Access the PDF export tool: Click the 'Export to PDF' button on the quick access toolbar, or navigate to Menu > Export to PDF.
- 3. Confirm export settings: Ensure your layout and page ranges are correct in the dialog box, then click 'Export' to generate a highly accurate PDF.

Frequently Asked Questions
How can I check font embeddability on a Windows PC?
Open the Windows Control Panel, navigate to 'Appearance and Personalization', and click on 'Fonts'. Select the font you want to check and look at the bottom details pane or the 'Font embeddability' column. If it says 'Restricted', the font cannot be embedded into a PDF without a license upgrade.
Will using the 'Print to PDF' feature instead of 'Save As' fix font substitutions?
In some cases, using the virtual 'Print to PDF' printer can bypass minor conversion glitches by flattening the text into vectors. However, if a font has strict DRM or licensing restrictions, even the Print to PDF function may fail to render the font correctly or may refuse to process the print job.
What happens if I send the PDF to someone who already has the restricted font installed?
If a restricted font is not embedded in the PDF, the recipient's PDF reader will look for that font on their local machine. If they happen to have the exact same font installed, the PDF will likely display correctly for them. If they do not, their reader will substitute it with a default system font.
