How to Fix Font Changes When Converting Word to PDF
Question details
The user experiences font changes, substitutions, or text distortions when creating a PDF from Word or Timeslips.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Saving or exporting a Microsoft Word document or Timeslips file as an Adobe PDF.
- Observed behavior
- Original fonts are not properly embedded in the generated PDF, causing the PDF reader to substitute them with distorted or incorrect default fonts like Times New Roman.
Ensure that the fonts used in your original document are properly installed on your system and do not have licensing restrictions that prevent them from being embedded in a PDF.
Clear the Adobe Font Cache Files
Deleting corrupted font cache files forces Adobe Acrobat to rebuild its font directory, which frequently resolves font substitution and distortion issues.
Adobe applications use specific cache files to load fonts quickly. If these files become outdated or corrupted, the PDF creation process may fail to recognize properly installed fonts, resulting in forced substitutions in the final document.
Fully close Adobe Acrobat, Microsoft Word, Timeslips, and any other running document editors.
Open File Explorer and use the search bar to find files named 'AdobeFnt##.lst', where '##' represents a two-digit number (for example, AdobeFnt16.lst).
Select all the located 'AdobeFnt##.lst' files and delete them. Do not worry about losing data; Acrobat will safely regenerate fresh versions of these files the next time it runs.
Reopen your Word document and attempt to use the 'Save as Adobe PDF' function again to see if the fonts are now correctly preserved.
Force Font Embedding in PDF Settings
Modifying your PDF export preferences guarantees that the original fonts are bundled directly inside the PDF file, preventing the reader from guessing or replacing them.
Repair or Reinstall Adobe Acrobat
If clearing the cache and embedding fonts fails, the Adobe Acrobat installation itself may be corrupted and requires a repair.

Frequently Asked Questions
Why does my font look completely different after saving as a PDF?
This usually happens when the original font is not properly embedded into the PDF file. If the PDF reader cannot find the embedded font or the font installed on the local system, it substitutes it with a default system font, which can disrupt the layout and distort the text.
Will deleting AdobeFnt##.lst files cause me to lose my installed fonts?
No. Deleting these specific .lst cache files will not delete your actual font files (.ttf or .otf) from your computer. Adobe applications simply use these temporary lists to load fonts faster, and they will automatically recreate them upon restart.
How do I check if my fonts are successfully embedded in my PDF?
Open your converted PDF in a PDF reader like Acrobat or WPS PDF. Go to 'File', select 'Properties', and click on the 'Fonts' tab. This section will list all the fonts used in the document and clearly state 'Embedded' or 'Embedded Subset' next to each successfully bundled font.
Can I prevent font issues without using Adobe Acrobat?
Yes. You can use alternative, fully integrated software like WPS Office, which natively supports accurate font preservation and automatic embedding during PDF conversion without requiring external add-ins.
