Fix Excel Font Loss When Combining PDFs in Adobe Acrobat
Question details
Users experience missing characters or corrupted text when merging Excel files into a PDF document using Adobe Acrobat.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Combining multiple documents, including Excel spreadsheets, into a single PDF file using the Acrobat Combine Files tool.
- Observed behavior
- Acrobat's automated merge process fails to apply custom print settings to Excel files, causing fonts to remain unembedded and resulting in text corruption in the final PDF.
Ensure that all custom or non-standard fonts used in your Excel workbook are correctly installed on your local computer before attempting to convert or merge the files.
Pre-convert Excel to PDF with Embedded Fonts
Manually print the Excel spreadsheet to a PDF file using configured printer settings that force font embedding before combining it with other files.
Acrobat's 'Combine Files' tool uses default background settings that often skip embedding document fonts for Excel files to save space. By converting the Excel file to a PDF manually first, you ensure the fonts are locked into the document.
Launch Microsoft Excel and open the spreadsheet that is causing font issues during the merge process.
Navigate to 'File' > 'Print' and select 'Adobe PDF' (or your preferred PDF virtual printer) from the Printer dropdown menu.
Click on 'Printer Properties'. In the Adobe PDF Settings tab, ensure 'Rely on system fonts only; do not use document fonts' is unchecked. Select a conversion setting like 'High Quality Print' that embeds all fonts.
Click 'Print' to generate the standalone PDF file. Review this new PDF to verify all characters render correctly.
Open Adobe Acrobat, select 'Combine Files', and add your newly generated PDF instead of the original Excel file to merge your documents without font loss.
Use the Acrobat PDFMaker Add-in in Excel
Utilize the dedicated Acrobat ribbon inside Excel to customize conversion settings prior to merging.

Frequently Asked Questions
Why does Adobe Acrobat lose my Excel fonts when combining files directly?
When you use the 'Combine Files' feature, Acrobat relies on background conversion presets that may not force font embedding for Office documents. If the original fonts aren't mapped properly during this automated process, the characters can appear corrupted or go missing.
Can I force Adobe Acrobat to embed all fonts by default?
Yes. You can modify the Adobe PDF printer preferences in your Windows 'Printers & Scanners' settings. By changing the Default Settings to a preset like 'High Quality Print', Acrobat will automatically embed all available fonts during standard conversions.
Does this font issue happen with standard fonts like Arial or Times New Roman?
Typically, standard system fonts do not cause issues because Acrobat can easily find and map them. Font corruption mostly occurs when your Excel file uses custom, downloaded, or specific corporate fonts that Acrobat fails to locate during the quick merge process.
