How to Open Exported Word PDFs in Adobe Reader Instead of a Browser
Question details
Users want PDFs exported from Microsoft Word with the 'Open file after publishing' option enabled to automatically open in Adobe Reader rather than a web browser like Microsoft Edge.

- Product
- Microsoft Word
- Device & OS
- Windows
- Scenario
- Exporting a Word document to PDF and automatically opening the published file for review.
- Observed behavior
- The newly exported PDF automatically opens in a separate web browser tab (such as Edge) instead of the preferred local application like Adobe Reader or Acrobat.
Ensure that Adobe Reader or Adobe Acrobat is installed on your computer and updated to the latest version before modifying your Windows file associations.
Set Adobe Reader as the Default PDF App via the Context Menu
The quickest way to fix this issue is by changing the default program for PDF files directly from the Windows right-click context menu.
Microsoft Word relies on your operating system's default file association to decide which program opens a PDF after publishing. By changing this default setting, Windows will redirect all PDF opening requests to Adobe Reader.
Find any existing PDF file on your computer using Windows File Explorer.
Right-click the PDF file, hover over 'Open with' in the context menu, and select 'Choose another app'.
Click on Adobe Acrobat or Adobe Reader from the list of available applications.
Check the box that says 'Always use this app to open .pdf files' (or click 'Always' in Windows 11) and click OK.

Update File Associations in Windows Settings
If the context menu method does not work or your preferences keep getting reset, you can explicitly enforce the default app for the .pdf extension within Windows Settings.
Export and View PDFs Seamlessly with WPS Office
Avoid Windows file association conflicts entirely. WPS Office features a built-in PDF reader and editor. When you export a document to PDF, it opens immediately in the same unified tabbed workspace, streamlining your workflow.
- 1. Open your document: Launch WPS Writer and open the document you wish to convert.
- 2. Export to PDF: Go to the Menu and click on 'Export to PDF'.
- 3. Enable auto-open: Ensure the 'Open after export' option is checked in the dialog box, then click 'Export'.
- 4. View instantly: The exported PDF will immediately open as a new tab right inside the WPS Office window.

Frequently Asked Questions
Why does Windows keep changing my default PDF app back to Microsoft Edge?
Windows updates, Edge browser updates, or strict organizational IT policies can sometimes reset file associations. If you are on a company computer, check with your IT administrator to see if a policy is enforcing Microsoft Edge as the default PDF viewer.
Does this issue happen because my files are synced with OneDrive or SharePoint?
No, the browser issue is strictly related to how Windows handles the .pdf file extension association locally. Whether your original Word files are backed up locally, on OneDrive, or SharePoint does not impact the PDF export behavior.
What does 'Open file after publishing' mean in Word?
It is a checkbox option in the Export to PDF dialog that commands Windows to immediately open the newly created PDF file using the system's default PDF viewer, allowing you to quickly review the exported document.
