How to Fix Font Changes When Converting DOCX to PDF
Question details
The user needs to prevent custom typography from being substituted or formatting from breaking when converting a Word document to a PDF.

- Product
- PDF Converter
- Device & OS
- not provided
- Scenario
- Converting a DOCX file containing non-standard fonts (such as Adobe Hebrew) into a PDF file for accurate sharing or print production.
- Observed behavior
- The resulting PDF does not retain the original font, which causes character spacing issues and disrupts the layout of text boxes within the document.
Ensure that the necessary custom fonts are fully installed on the local system you are using to edit and convert the document.
Embed Fonts in the DOCX File Before Conversion
Embedding the required fonts directly into the Word document ensures that external conversion services can access the exact typography, preventing layout-breaking substitutions.
PDF conversion heavily depends on the fonts available to the conversion service. If a font like Adobe Hebrew is missing from the converter's library, the service will substitute it with a default system font. Because different fonts have unique character widths and kerning, this substitution shifts text and misaligns text boxes.
Open your DOCX file in your word processor. Click on 'File' in the top-left corner and select 'Options' from the menu at the bottom.
In the Options dialog box, click on the 'Save' tab located in the left pane.
Scroll down to the 'Preserve fidelity when sharing this document' section. Check the box labeled 'Embed fonts in the file'.
Check 'Do not embed common system fonts' to keep your document file size manageable while ensuring custom fonts are saved.
Click 'OK' to apply the settings. Save your document, and then attempt the PDF conversion again.

Use Built-in Native PDF Export
Using your word processor's built-in PDF export feature utilizes local system fonts rather than relying on a third-party server font library.
Use WPS Office for Accurate DOCX to PDF Conversion
WPS Office features a powerful, built-in PDF conversion engine that natively understands DOCX formatting. It accurately preserves your original fonts, spacing, and text-box layouts without requiring complex embedding setups or third-party online converters.
- 1. Open Document in WPS Writer: Download and install WPS Office. Launch WPS Writer and open your DOCX file.
- 2. Access Export Feature: Click on the 'Menu' button in the top left corner of the application.
- 3. Select Export to PDF: Hover over the menu and click 'Export to PDF' from the dropdown options.
- 4. Configure Settings: In the Export to PDF dialog, verify your page range and save path. The preview will show your precise original layout.
- 5. Generate PDF: Click the 'Export to PDF' button to save your document. The output will perfectly match the fonts and spacing of the DOCX file.

Frequently Asked Questions
Why do text box layouts change when I convert a Word document to PDF?
Text boxes rely on the exact dimensions of the text inside them. If a custom font is missing during conversion, the software uses a fallback system font. Because the fallback font has different letter widths and line heights, the text expands or shrinks, which forces the text boxes to shift or push content onto new pages.
How can I check if my custom fonts are successfully embedded in a PDF?
Open your exported PDF in a standard PDF viewer like WPS PDF or Adobe Acrobat. Press Ctrl+D (or go to File > Properties) and click on the 'Fonts' tab. You will see a list of every font used; successfully embedded fonts will have '(Embedded)' or '(Embedded Subset)' listed next to their names.
Does embedding fonts make my DOCX file larger?
Yes, embedding fonts attaches the actual font data to your document file, increasing its overall size. To minimize this impact while maintaining formatting, you can check the 'Do not embed common system fonts' option, which excludes standard fonts like Arial or Calibri from being saved in the file.
What should I do if my custom font cannot be embedded due to licensing restrictions?
If a font has restricted licensing (TrueType or OpenType DRM), Word cannot embed it. You can either replace the restricted font with a visually similar open-source font (like Google Fonts) or print the document directly to a virtual PDF printer using your local system, which bypasses file-embedding restrictions.
