Fix Adobe Acrobat and Word Crashing When Combining Word Documents
Question details
The user needs to combine multiple Word documents into a PDF but experiences system freezing or crashing during the process.
- Product
- Adobe Acrobat Pro and Microsoft Word
- Device & OS
- not provided
- Scenario
- Combining multiple Word documents directly into a single PDF file.
- Observed behavior
- Adobe Acrobat Pro 2017 and Microsoft Word 2016 crash or freeze when attempting to combine the Word documents into a PDF, though creating individual PDFs and merging existing PDFs works fine.
Ensure you have saved all changes to the Word documents you are attempting to merge and close any unnecessary background applications to free up system memory.
Reset Adobe Acrobat Preferences
Corrupted preference settings in Acrobat can interfere with the Word-to-PDF conversion engine, causing the application to crash. Resetting them forces the program to create clean configuration files.
Because combining existing PDFs works successfully, the core issue is likely related to Acrobat's specific preferences or its integration with Microsoft Office during the conversion phase.
Ensure that both Adobe Acrobat Pro and Microsoft Word are completely closed.
Open File Explorer and navigate to your AppData roaming folder. The Acrobat preferences are typically located at C:\Users\[Your Username]\AppData\Roaming\Adobe\Acrobat\[Version].
Rename the preferences folder (e.g., to 'Acrobat_old') or move it to your desktop. This hides it from Acrobat without permanently deleting it.
Open Adobe Acrobat again. The software will automatically generate a fresh default preferences folder. Attempt to combine your Word documents again.
Repair the Acrobat PDFMaker Add-in in Word
A malfunctioning COM add-in within Microsoft Word can cause freezes when Acrobat tries to communicate with Word to extract and convert the document data.
Convert Documents Individually Before Combining
Bypass the simultaneous conversion and combination process by separating the workflow into two manageable steps.

Frequently Asked Questions
Why does Adobe Acrobat freeze when converting Word to PDF?
This commonly occurs due to a corrupted Acrobat PDFMaker COM add-in within Microsoft Word, conflicting background processes, or outdated software versions that fail to communicate properly during the conversion.
How do I fix the Acrobat PDFMaker add-in missing or crashing in Word?
You can try disabling and re-enabling the add-in by going to File > Options > Add-ins > COM Add-ins in Word. If that fails, repairing your Adobe Acrobat installation via the Windows Control Panel often restores the integration.
Can I combine Word documents without using Adobe Acrobat?
Yes. You can use integrated office suites like WPS Office that offer native PDF merging tools, or you can utilize secure online PDF combiners that process the files on a cloud server rather than relying on your local desktop resources.
Could the file size be causing the crash during the merge?
Yes. Word documents containing extremely large or uncompressed images require significant memory to convert. Try compressing pictures in Word (Picture Format > Compress Pictures) before attempting the PDF combination.
