How to Fix Low Image Resolution When Converting Word to PDF
Question details
The user needs to prevent image resolution loss when converting a Word document containing high-quality images to a PDF file for professional printing.
- Product
- PDF Pack / Word
- Device & OS
- not provided
- Scenario
- Converting a Word document with 300 DPI images to a PDF for publishing on CreateSpace.
- Observed behavior
- The resulting PDF is rejected by the publishing platform because the conversion process automatically downsampled the images, resulting in low resolution.
Ensure that the original images inserted into your Word document are actually 300 DPI or higher, as the PDF conversion process cannot enhance the resolution of originally low-quality images.
Disable Default Image Compression in Word
Prevent the word processor from automatically downsampling your images before the PDF conversion starts.
By default, word processors automatically compress images to reduce the overall document file size. Disabling this feature ensures that your original 300 DPI images remain intact in the source document before being passed to the PDF converter.
Click on 'File', select 'Options' at the bottom of the menu, and then click on 'Advanced'.
Scroll down to the 'Image Size and Quality' section and check the box labeled 'Do not compress images in file'.
Change the default resolution dropdown menu to 'High fidelity' and click 'OK' to save your changes.
Use Print-Quality PDF Export Settings
Ensure the PDF conversion engine is configured to optimize for printing rather than small file sizes.
Export High-Resolution PDFs with WPS Office
WPS Office provides a seamless Word-to-PDF conversion experience that preserves your original image quality, ensuring documents easily meet the strict 300 DPI requirements for publishing platforms like CreateSpace.
- 1. Open document in WPS Writer: Launch WPS Office and open your source document containing the high-resolution images.
- 2. Access PDF Export: Navigate to the 'Tools' tab on the top ribbon and select 'Export to PDF'.
- 3. Configure high-quality settings: Click on 'Advanced Settings' within the export dialog and ensure the output is set to standard or high-quality publishing presets.
- 4. Export the file: Click 'Export' to generate a print-ready PDF that retains your original 300 DPI images.
Frequently Asked Questions
Why does my PDF look blurry after converting from a Word document?
Default PDF converters often automatically downsample images to reduce the final file size for email or web use. If this compression is active, high-resolution images are scaled down, resulting in a blurry or pixelated PDF when printed.
How do I check the DPI of my converted PDF before uploading to CreateSpace?
You can check the effective DPI of images within a PDF using Adobe Acrobat Pro's Preflight tool, or by using the Output Preview feature to inspect individual object properties and confirm they meet the 300 DPI threshold.
What is the recommended image resolution for professional book printing?
For professional physical printing services like CreateSpace (now Amazon KDP), images should be at least 300 DPI (dots per inch) to ensure crisp, high-quality results without visible pixelation.
