Question details
The user wants to prevent Adobe Express from automatically opening PDF files and needs to restore Adobe Acrobat Reader as the default PDF application.

- Product
- Adobe Express, Acrobat Reader
- Device & OS
- not provided
- Scenario
- Opening standard PDF files locally from the device or clicking PDF links within a web browser.
- Observed behavior

Verify whether this issue happens when opening PDFs locally on your hard drive or when clicking PDF links within a web browser, as the settings to fix them differ.
Set Adobe Acrobat Reader as the Default App in System Settings
Change your operating system's default file associations so that all PDF documents automatically open in Acrobat Reader instead of Adobe Express.
Often, installing a new Adobe product or running a system update can silently change your default file associations. You can manually override this by resetting the default app for all .pdf files at the system level.
Find any standard PDF file saved locally on your computer's desktop or within your File Explorer.
Right-click on the PDF file, hover over 'Open with' in the context menu, and click on 'Choose another app'.
Scroll through the list of applications and click on 'Adobe Acrobat Reader'. If you don't see it, you may need to click 'More apps' to reveal it.
Check the box at the bottom that says 'Always use this app to open .pdf files' (on Windows) or click 'Change All' (on Mac), then click 'OK'.

Disable Adobe Express PDF Viewer in Web Browsers
Adjust your browser settings if PDFs are opening in Adobe Express only when you click them on the internet.
Change Default Handler within Acrobat Reader
Trigger the default app assignment directly from within Adobe Acrobat Reader's internal preferences menu.
Use WPS Office as Your Default PDF Viewer
Bypass Adobe application conflicts entirely by setting WPS Office as your default PDF reader. WPS provides a lightweight, fast, and feature-rich PDF experience for viewing, editing, and annotating all your documents without unexpected app switches.
- 1. Download WPS Office: Download and install WPS Office from the official website.
- 2. Locate Your PDF: Right-click any PDF file stored on your computer.
- 3. Choose Another App: Hover over 'Open with' and select 'Choose another app' from the dropdown menu.
- 4. Select WPS Office: Choose 'WPS Office' from the software list.
- 5. Set as Default: Check the box for 'Always use this app to open .pdf files' and click 'OK'.

Frequently Asked Questions
Why did Adobe Express suddenly become my default PDF viewer?
This often happens after a recent software update, an accidental click on a promotional prompt, or if Adobe Express was newly installed and automatically set itself as the default application during the setup process.
Will changing the default PDF viewer alter my existing files?
No, changing the default application only changes the software program used to view the files. It does not alter the content, layout, format, or data within your existing PDF documents.
How do I fix this if it only happens on specific PDF files?
If only certain PDFs open in Express, those specific files might have been manually associated with it. You can fix this by right-clicking one of the affected files, selecting 'Open with' > 'Choose another app', picking Acrobat Reader, and checking 'Always use this app'.
Can a browser extension force PDFs to open in Adobe Express?
Yes, if you have the Adobe Express browser extension installed and enabled, it may hijack PDF web links. You can resolve this by managing your browser extensions and toggling off or removing the Adobe Express add-on.
