How to Fix Acrobat Slowing Down Microsoft Word During PDF Conversion
Question details
Microsoft Word experiences significant slowdowns or lag when using Adobe Acrobat to convert PDF files into DOC format.

- Product
- Adobe Acrobat / Microsoft Word
- Device & OS
- Older Windows system
- Scenario
- Converting a PDF file to a Word document (DOC) using Adobe Acrobat.
- Observed behavior
- Microsoft Word becomes unresponsive, sluggish, or extremely slow during and after the PDF to DOC conversion process.
Ensure you have saved and closed any open documents in Microsoft Word to prevent data loss in case the application freezes or crashes during the troubleshooting process.
Optimize System Resources and Update Software
Freeing up memory and ensuring your software is up to date can resolve performance bottlenecks on older Windows systems.
PDF conversion requires significant processing power and memory. On older machines, running multiple applications simultaneously can starve Acrobat and Word of the resources they need to perform conversions smoothly.
Close all unnecessary applications and browser tabs running in the background to free up RAM and CPU resources for the conversion.
Open Adobe Acrobat, go to "Help" in the top menu, select "Check for Updates," and install any available software updates.
Open Microsoft Word, navigate to "File" > "Account" > "Update Options," and click "Update Now" to ensure you have the latest performance patches.
Restart your computer to clear the system cache, then attempt the PDF to Word conversion again.

Disable Unnecessary Acrobat Add-ins in Word
Conflicting or resource-heavy add-ins can cause Word to lag during file conversions.
Convert the PDF in Smaller Sections
Splitting a large or complex PDF into smaller chunks reduces the processing power required for conversion.
Convert PDFs to Word Smoothly with WPS Office
Skip the heavy processing loads of Acrobat and Microsoft Word. WPS Office features a built-in, lightweight PDF to Word converter that runs smoothly even on older Windows systems, ensuring accurate formatting without the lag.
- 1. Launch WPS Office: Download and open WPS Office, then click on the "PDF" tab in the main dashboard.
- 2. Open your PDF: Locate and open your target PDF file within the WPS PDF reader.

- 4. Adjust settings: Choose your desired conversion settings, such as the specific page range and the output destination folder.
- 5. Start conversion: Click "Start" to quickly convert the document to DOC or DOCX format without slowing down your computer.

Frequently Asked Questions
Why does converting large PDFs use so much computer memory?
PDFs with high-resolution images, complex vector graphics, or embedded fonts require significant computational power to render and translate into editable text formats like Word. This process can quickly consume available RAM on older systems, leading to slowdowns.
Can I convert PDF to Word without using Adobe Acrobat?
Yes, you can use built-in tools in modern Office suites like WPS Office, which natively supports fast PDF to Word conversion. Alternatively, you can utilize online conversion services that process the file on cloud servers rather than relying on your local machine's hardware.
Will disabling the Acrobat add-in in Word stop me from saving documents as PDF?
No. Disabling the COM add-in typically just removes the dedicated Acrobat ribbon in Word. You can still save or export your Word documents as PDFs using Word's native "Save As" or "Export" features.
How much RAM is recommended for smooth PDF to Word conversions?
While basic text-only conversions can run on 4GB of RAM, having at least 8GB of RAM is recommended for converting large or complex PDF files smoothly without causing other applications to lag.
