Fix Custom Fonts Not Embedding in Word to PDF Conversion
Question details
A custom FontForge font embedded in a Word document fails to carry over during PDF conversion, resulting in a substitute font being displayed in the output PDF file.
- Product
- Word to PDF
- Device & OS
- not provided
- Scenario
- Converting a Word document containing custom or third-party fonts (such as FontForge creations) into a PDF file format.
- Observed behavior
- The generated PDF does not embed the custom font, causing the document's appearance to change as a default system font is substituted in its place.
Verify the embedding permissions of your custom font in the operating system, as some fonts have strict licensing flags that block embedding during PDF creation.
Force Font Embedding via PDF/A Export Settings
Use the PDF/A compliance setting during Word document export, which strictly mandates all fonts to be embedded in the output file.
Standard PDF conversions might skip embedding certain custom fonts to reduce file size. By exporting the document as a PDF/A (an ISO-standardized version of the Portable Document Format specialized for digital preservation), you force the source application to embed every font used.
Navigate to File > Options > Save. Under the 'Preserve fidelity when sharing this document' section, check 'Embed fonts in the file' and uncheck 'Do not embed common system fonts'.
Go to File > Save As, choose your destination folder, and select 'PDF' from the 'Save as type' drop-down menu.
Click the 'Options...' button in the Save As dialog box. Under 'PDF options', check the box for 'ISO 19005-1 compliant (PDF/A)' and click OK.
Click 'Save' to generate the PDF. Open the resulting file to ensure the custom fonts are displayed correctly.
Modify Font Embeddability Settings in FontForge
Change the internal embedding restrictions of your custom font so that PDF conversion engines are allowed to embed it.
Embed Fonts Post-Conversion using Adobe Acrobat
Use the Preflight tool in a professional PDF editor to embed fonts into an already converted PDF file.
Ensure Perfect Font Retention with WPS Office PDF Converter
WPS Office features a robust native PDF converter that automatically retains custom fonts, ensuring your exported PDFs look exactly like the original document without requiring complex configurations.
- 1. Open Document: Launch WPS Writer and open your Word document containing the custom fonts.
- 2. Access Export Tool: Navigate to the 'Tools' tab on the top ribbon and select 'Export to PDF'.
- 3. Configure Settings: In the export dialog, verify your save path. The built-in engine automatically handles font embedding by default.
- 4. Export PDF: Click 'Export to PDF' to generate the file with all custom fonts securely embedded for perfect fidelity.
Frequently Asked Questions
Why does the font change when converting Word to PDF?
If a custom font is not embedded in the original document, or if the conversion tool drops it to save space, the PDF reader will substitute it with a default system font (like Arial or Helvetica) to ensure the text remains readable.
How do I check if my fonts are successfully embedded in a PDF?
Open your PDF file in a PDF reader, go to Document Properties (usually File > Properties), and navigate to the Fonts tab. It will display '(Embedded)' or '(Embedded Subset)' next to the font name if the embedding was successful.
Does checking 'Embed fonts in the file' in Word guarantee PDF embedding?
Not always. While it embeds the font in the Word (.docx) file, the PDF conversion engine still dictates the final PDF output. Exporting the file with 'PDF/A compliant' settings ensures the PDF engine forces the embed.
