How to Fix Incorrect Font Weight When Saving Document as PDF
Question details
Text formatted with specific third-party fonts, such as Google Fonts, loses its bold weight during PDF export even when font embedding is enabled.

- Product
- WPS PDF
- Device & OS
- not provided
- Scenario
- Exporting or saving a document containing custom or downloaded fonts as a PDF file.
- Observed behavior
- The bold text formatting is lost, causing the font to display as thin or incorrectly weighted in the resulting PDF document.
Verify that the true bold variant of your font file (e.g., FontName-Bold.ttf) is actively installed on your system, rather than relying on your word processor to artificially simulate a bold effect.
Test Font Compatibility and Check PDF Viewers
Determine whether the font weight issue originates from the specific Google Font file or the PDF viewing application being used.
PDF generation engines sometimes struggle to render bold formatting for third-party fonts if the font family lacks a dedicated bold file. Additionally, certain PDF readers may interpret and render embedded fonts differently, making the text appear thin.
Highlight the affected text and change it to a standard system font like Arial or Times New Roman. Apply bold formatting and export the document to PDF to see if the weight is properly retained.
Open the generated PDF file using different applications such as WPS PDF, Adobe Acrobat, or your web browser to check if the bold text renders correctly in other environments.
If the issue exclusively occurs with the specific Google Font and persists across all PDF viewers, it is likely a third-party font compatibility problem. Visit Google Fonts Support (https://developers.google.com/fonts/faq) to report the issue.

Frequently Asked Questions
Why does my PDF text look completely different from the original document?
This typically happens when fonts are not embedded during the PDF export. If the device viewing the PDF lacks the original font, it will substitute it with a standard system font, which alters the layout and appearance. Always ensure 'Embed Fonts' is checked before exporting.
How do I correctly install a Google Font to ensure bold works?
Download the font family from Google Fonts, extract the downloaded ZIP file, and ensure you right-click and install all specific font weight files (including the '-Bold' or '-Black' variants), rather than just the Regular weight file.
Does WPS Office support custom third-party fonts?
Yes, WPS Office fully supports any TrueType (TTF) or OpenType (OTF) font installed on your operating system. Once you install a new font locally, simply restart WPS Office, and the new font will appear in the typography dropdown menu.
