How to Fix Missing Fonts and Incomplete Pages in Combined PDFs
Question details
Users encounter missing font warnings and incomplete page rendering when opening a combined PDF document on different computers.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Viewing or sharing a PDF document that was recently combined from multiple source files.
- Observed behavior
- The PDF reports missing fonts (such as Arial Narrow), and some characters or page contents display incorrectly or inconsistently across various devices.
Verify if the missing font (e.g., Arial Narrow) is installed on your local computer system before attempting to edit or re-export the PDF file.
Recreate the PDF with Embedded Fonts
The most reliable way to fix missing fonts and rendering issues is to embed the fonts during the original PDF creation process.
When merging PDFs, if the source files reference fonts that are not embedded, the new document may fail to display correctly on devices missing those specific fonts. Re-exporting the original files with strict font embedding ensures universal compatibility.
Open the original documents in their native applications (e.g., Microsoft Word, Adobe InDesign).
Go to the 'File' menu, select 'Export' or 'Save As', and choose PDF. Look for 'Options' or 'Advanced Settings'.
Check the box that says 'Embed all fonts' or 'Subset embedded fonts' to ensure all characters are bundled within the file.
Save the new PDF files and combine them again using your PDF editor. Test the final document on another computer.
Flatten or Print to PDF
If you do not have access to the original source files, flattening the PDF can lock the visual appearance and bypass missing font errors.

Frequently Asked Questions
Why does a combined PDF display fine on one computer but not another?
This usually happens when the PDF uses a specific font that wasn't embedded into the document file. If the viewing computer doesn't have that exact font installed in its system directory, the PDF reader substitutes it with a default font, causing formatting errors or missing characters.
How can I check if a font is embedded in my PDF?
Open the PDF in your reader, navigate to 'Document Properties' (typically found under the File menu), and click on the 'Fonts' tab. It will list all the fonts used in the document and explicitly state 'Embedded' or 'Embedded Subset' next to them.
Can I fix a missing font error without the original Word or InDesign file?
Yes. You can bypass the issue by opening the PDF on a computer where it displays correctly and using the 'Print to PDF' function to flatten the document. Alternatively, you can use a PDF editor's text tool to manually select the text and change it to a standard system font like Arial or Times New Roman.
