How to Speed Up Batch Word to PDF Conversion in Acrobat Pro
Question details
The user needs to improve the processing speed when batch converting hundreds of Word documents to PDF in Acrobat Pro 2017.

- Product
- Adobe Acrobat Pro 2017
- Device & OS
- not provided
- Scenario
- Converting a large batch of Word documents into PDF files simultaneously.
- Observed behavior
- The batch conversion process is exceptionally slow and is frequently interrupted by ink annotation warnings requiring manual dismissal for each file.
Before starting the batch conversion, ensure your Word documents do not contain unresolved ink annotations that may trigger warnings, and place all files into a single local folder to reduce processing overhead.
Configure PDF Conversion Presets in Preferences
Adjusting import-setting presets minimizes background processing and prevents unnecessary warnings from interrupting the batch sequence.
Acrobat's default settings may attempt to embed complex fonts, high-resolution images, and retain specific markup annotations which drastically slows down batch conversions.
By defining custom import settings, you bypass resource-heavy processes like checking for ink annotations.
Open Adobe Acrobat Pro 2017, click on the 'Edit' menu at the top, and select 'Preferences'.
In the left-hand Categories pane, click on 'Convert to PDF'.
Select 'Microsoft Word' under the converting formats list and click the 'Edit Settings' button.
Disable settings related to importing ink annotations or complex markups, test lower image resolution settings if applicable, and click 'OK' to save.
Use File Explorer Context Menu via Adobe PDFMaker
Selecting files directly in Windows File Explorer and converting them via the right-click menu uses the Adobe PDFMaker add-in, which can bypass slower internal Acrobat batch actions.
Batch Convert Word to PDF Fast with WPS Office
WPS Office features a robust, built-in batch conversion tool that processes multiple Word documents to PDF rapidly without being interrupted by complex annotation warnings.
- 1. Launch WPS Office: Open WPS Office and select 'PDF' from the main navigation panel.
- 2. Select Word to PDF: Click on 'Word to PDF' located in the PDF toolkit menu.
- 3. Import Multiple Files: Click 'Add Files' or drag and drop your entire batch of Word documents into the conversion window.
- 4. Start Batch Conversion: Choose your desired output folder at the bottom and click 'Convert' to process all files instantly.

Frequently Asked Questions
Why does Acrobat keep warning me about ink annotations during conversion?
Acrobat triggers this warning when it detects digital drawing or handwriting markups (ink annotations) in the Word document. The software pauses the conversion to ask how you want to handle these elements, which interrupts automated batch processing.
Can I batch convert Word to PDF without opening Acrobat?
Yes, by utilizing the Windows right-click context menu. Select all your Word files in File Explorer, right-click, and select 'Convert to Adobe PDF'. This uses the background PDFMaker add-in, though you must have Acrobat installed.
How do I turn off warnings in Acrobat Pro batch processing?
You can minimize warnings by altering your default conversion presets. Navigate to Edit > Preferences > Convert to PDF, select Microsoft Word, click Edit Settings, and uncheck options that prompt the software to ask for user input on unresolvable elements like missing fonts or complex markups.
Is there a faster alternative to Acrobat for batch converting .docx to .pdf?
Yes, dedicated office suites like WPS Office feature built-in batch conversion tools that are often faster and bypass the strict pre-flight checks Acrobat performs, making them ideal for converting hundreds of text documents quickly.
