Fix Roboto Font Style Changes When Exporting Word and PowerPoint to PDF
Question details
Roboto Black bold italic font formatting changes to regular text when exporting Word or PowerPoint documents to PDF.

- Product
- Word, PowerPoint
- Device & OS
- Windows
- Scenario
- Exporting documents to PDF after installing a Windows update.
- Observed behavior
- Font styles such as Roboto Black bold italic revert to standard regular text in the exported PDF file, even after reapplying the font style or completely reinstalling the fonts.
Verify that you have the latest updates installed for both your Windows operating system and your Office suite, and ensure the Roboto font family is correctly installed in your system's font directory.
Use 'Print to PDF' Instead of Exporting
Using the Print to PDF feature utilizes a different rendering method and can often bypass the font formatting issues encountered during standard PDF exports.
The built-in 'Save as PDF' or 'Export' functions sometimes fail to render specific font weights after system updates. By printing to a virtual PDF printer, you force the system to render the fonts exactly as they appear on the screen.
Open your Word or PowerPoint document containing the Roboto font, navigate to the 'File' tab, and select 'Print'.
Under the Printer dropdown menu, select 'Microsoft Print to PDF' instead of your physical printer.
Click the 'Print' button, choose a save location on your computer, and check the newly created PDF to see if the Roboto Black bold italic font style is retained.

Isolate the Issue with a New Document
Testing a completely new document helps determine whether the font rendering issue is related to corrupted settings in older files or a system-wide software bug.
Escalate to Support for Investigation
Because this issue involves cross-application font rendering failures after a Windows update, it may require an official patch from the Microsoft 365 support team.
Use WPS Office for Reliable PDF Exports
If Microsoft Office continues to drop font formatting during PDF export, WPS Office provides a lightweight, highly compatible alternative. It handles custom fonts efficiently, ensuring that your exported PDFs look exactly as designed without losing bold or italic styling.
- 1. Open your document in WPS Office: Launch WPS Office and open your existing Word or PowerPoint file containing the Roboto fonts.
- 2. Use the built-in PDF exporter: Click on the 'Menu' button in the top left corner and select 'Export to PDF' from the dropdown list.
- 3. Save the preserved file: Choose your save location and export. WPS Office will reliably retain your bold and italic font formatting.

Frequently Asked Questions
Why do custom fonts like Roboto change to regular text in PDFs?
This happens when the application's PDF export engine fails to properly embed specific font weights or styles. It is often caused by changes in system font rendering after an OS update.
Will reinstalling the Roboto font fix the PDF export issue?
While reinstalling fonts can fix general display issues, it often does not resolve PDF export rendering failures if the root cause is a software update bug affecting the export engine itself.
How do I embed fonts in Word to prevent formatting loss?
You can embed fonts by navigating to File > Options > Save, and checking the box for 'Embed fonts in the file'. However, if the PDF exporter is failing due to a Windows update, this setting might still be bypassed during export.
