Fix Black Boxes Around Images When Converting Word to PDF
Question details
Images and objects in a Microsoft Word document turn black or develop black backgrounds after being exported to a PDF.
- Product
- Microsoft Word, Adobe Acrobat
- Device & OS
- Windows 10
- Scenario
- Converting a Word document that contains graphic images, particularly those placed inside table cells, into a PDF format using PDFMaker or Adobe Acrobat tools.
- Observed behavior
- The resulting PDF file displays completely blacked-out areas or black backgrounds around the inserted images and objects instead of their proper graphics.
Before attempting any fixes, save a backup copy of your original Word document to prevent accidental loss of formatting or images during the troubleshooting process.
Update Software and Use Native Export Options
Using outdated versions of Word or PDFMaker plugins can cause rendering bugs. Updating your software and utilizing Word's native PDF export feature often resolves graphical glitches.
Third-party add-ins like Acrobat PDFMaker can sometimes struggle to render complex formatting combinations, such as images within table cells. Switching to Microsoft's native PDF engine usually bypasses this issue.
Open Microsoft Word, navigate to File > Account, and check for Office updates to ensure you have the latest build. Do the same for Adobe Acrobat via Help > Check for Updates.
Instead of clicking the Acrobat tab, click on the 'File' tab in the top-left corner of Microsoft Word, then select 'Export' from the left-hand menu.
Click the 'Create PDF/XPS Document' button. Choose your save location, ensure 'Standard' optimization is checked, and click 'Publish' to generate the PDF.
Recreate or Flatten the Affected Images
If only specific images are turning black, the issue might be related to incompatible image formats, such as transparent PNGs or complex vector graphics.

Frequently Asked Questions
Why do transparent PNG images turn black when converted to PDF?
Transparency in images can sometimes be mishandled by older PDF conversion plugins. During the conversion process, the software attempts to 'flatten' the image but incorrectly renders the empty transparent layer as black. Converting the image to a flattened format like JPEG before inserting it usually prevents this.
Does placing images inside Word table cells affect PDF conversion?
Yes. Complex formatting layers, such as placing vector objects or transparent graphics inside table cells, can overload or trigger rendering bugs in plugins like PDFMaker, causing the entire cell or image to black out during the export process.
Can I use 'Print to PDF' to fix image black boxes?
Yes. If the 'Save As' or 'Export' functions result in black boxes, using the 'Print' function (Ctrl+P) and selecting 'Microsoft Print to PDF' as the printer forces the system to use a different rendering pipeline, which often preserves the image appearance correctly.
