How to Fix PDF File Size Increasing After Word Conversion
Question details
The user is experiencing a significant file size increase when converting a specific Word chapter to PDF at an 8x10-inch page size.
- Product
- Microsoft Word, Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Converting a Word document to PDF format using the Adobe PDF printer.
- Observed behavior
- The resulting PDF file is unusually large compared to similar chapters, but this inflation only happens with the Adobe PDF printer and not with Microsoft Print to PDF.
Before troubleshooting, ensure you have saved a backup copy of your original Word document and check if there are any uncompressed high-resolution graphics embedded exclusively in the problematic chapter.
Use the Acrobat Ribbon in Word to Create the PDF
Instead of using the standard print menu, utilizing the dedicated Acrobat add-in ribbon within Word ensures optimized file output.
The Adobe PDF printer acts as a virtual printer that can sometimes embed unnecessary print-spooling data or full font sets, inflating file sizes. Using the dedicated add-in bypasses this process and optimizes the output.
Launch Microsoft Word and open the specific chapter or document you want to convert.
On the top Word ribbon, click on the 'Acrobat' tab to access the dedicated PDF tools.
Click the 'Create PDF' button. Follow the prompt to name your file and save it to your desired location.
Resave the PDF in Adobe Acrobat
If the generated PDF is still too large, re-saving it directly inside Adobe Acrobat forces the program to discard redundant internal data.
Use Microsoft Print to PDF
Since the file size inflation is isolated to the Adobe PDF printer, utilizing Microsoft's native Print to PDF feature is a quick workaround.
Convert Word to PDF Efficiently with WPS Office
WPS Office offers a built-in, highly optimized Word to PDF converter that maintains exact document formatting without unnecessarily inflating the file size. It perfectly handles customized page sizes and image-heavy chapters.
- 1. Open your document in WPS Writer: Launch WPS Office and open the Word document you wish to convert.
- 2. Access the PDF export tool: Click on 'Menu' in the top-left corner, then select 'Export to PDF'.
- 3. Adjust export settings: In the dialog box, you can choose 'Common PDF' for standard quality or adjust image compression settings to keep the file size minimal.
- 4. Export the file: Click the 'Export to PDF' button to generate your highly optimized, perfectly sized PDF document.
Frequently Asked Questions
Why does the Adobe PDF printer make files larger than Microsoft Print to PDF?
The Adobe PDF printer often embeds complete font sets, high-resolution print graphics, and extra metadata for print-ready fidelity. This can drastically increase the file size compared to Microsoft's simpler compression methods.
Can embedded images cause sudden PDF file size inflation?
Yes. If your Word document contains uncompressed, high-resolution images, the Adobe PDF engine may process them at maximum print quality. Compressing pictures within Word before conversion usually prevents this.
How do I compress an existing PDF if it's already too large?
You can use the 'Save As Other' > 'Reduced Size PDF' feature in Adobe Acrobat, or use dedicated PDF compression tools like the one built into WPS PDF to shrink the file size without noticeable quality loss.
Does changing the page size to 8x10 affect the PDF file size?
Changing page dimensions shouldn't drastically increase the file size on its own. The increase is usually due to how the specific PDF engine scales graphics and processes print margins within that new layout.
