Reduce the Size of a PDF Exported from Microsoft Publisher
Question details
The user needs to reduce an unexpectedly large PDF exported from a relatively small Microsoft Publisher publication.

- Product
- Microsoft Publisher
- Device & OS
- not provided
- Scenario
- Exporting a Publisher publication to PDF while keeping the output small enough to share.
- Observed behavior
- After changing the fonts to Arial and reducing an oversized image, the Publisher file was 772 KB, but the exported PDF was still approximately 15.537 MB.
Decide whether the PDF is intended for screen viewing or professional printing, since lower-resolution images can reduce print quality. Check the current PDF export preset and identify any large images in the publication.
Export the publication with Minimum size and compress its images
Use this first when the PDF is primarily for email, downloads, or on-screen viewing.
In Publisher, select File > Export > Create PDF/XPS, then click Create PDF/XPS. In versions with a different layout, use File > Save As and select PDF as the file type.
In the PDF publishing dialog, click Options and select Minimum size from the available publishing presets. Confirm the setting, then publish the PDF with a new filename.
If the PDF is still too large, select a picture in the publication and open Picture Tools > Format > Compress Pictures. Choose the lowest resolution suitable for your use, such as Web or 96 ppi if available, and apply it to all pictures when appropriate.
Export the PDF again with Minimum size selected. Check its file size and open it to inspect small text, logos, and photographs before sharing it.

Rebuild the Publisher publication to remove problematic formatting
Use this if the PDF remains unusually large after lowering export quality and compressing images.
Use WPS Office to Work with Documents Alongside Publisher PDFs
WPS Office is a free, lightweight, easy-to-use alternative for everyday document work, with a familiar interface and Microsoft Office format compatibility for a smooth transition. It can open the PDF exported from Publisher, but it does not replace Publisher's native publication editing or fix Publisher's export settings.

Frequently Asked Questions
Why can a small Publisher file produce a much larger PDF?
Publisher and PDF store content differently. PDF export may embed fonts, retain high-resolution images, or convert complex formatting into additional PDF content. The source file size alone does not predict the exported PDF size.
Where is the Minimum size setting in Publisher?
Open File > Export > Create PDF/XPS, click Create PDF/XPS, and then open Options in the publishing dialog. Select Minimum size from the available presets. Some versions instead provide PDF export through File > Save As.
Is 96 dpi suitable for a Publisher PDF?
Around 96 dpi can be suitable for screen viewing when small file size matters more than image detail. It may make photographs or graphics look soft in print. Select a picture and check Picture Tools > Format > Compress Pictures for the available resolution settings.
What should I try if changing fonts and shrinking images does not help?
Create a new publication through File > New, transfer the text using Paste Special > Unformatted Text, and reapply the layout manually. Export a test page before rebuilding the whole document to see whether removing the original formatting reduces PDF size.
Can WPS Office fix the original Publisher file?
WPS Office does not provide native Publisher PUB editing and cannot change Publisher's PDF export settings. Export the publication to PDF in Publisher first, then open that PDF in WPS Office for review. Keep using Publisher for changes to the original publication.
