How to Change Default PDF Viewer in Windows 11

In Windows 11, you can set a default app for any type of files or links so that whenever you open the file or link type, Windows will automatically open it with the selected default app. For any new file type or link type that Windows hasn’t discovered, it will prompt you a dialog message to choose a default app the first time you open the new file type. As for PDF file type, by default, Windows 11 will open PDF file in Microsoft Edge (Edge does support opening PDF very well).

If you don’t like Edge to open your PDF files, you can change the default app to open PDF file to any app you want, for example, Chrome, Firefox, Adobe Acrobat Reader, office software, etc. This guide shows you how to change the default PDF viewer in Windows 11 to any other app you want.

In most cases, when you install a PDF viewer app or software such as Adobe Acrobat Reader DC (likely the most popular PDF viewer software globally), there is usually a step during the installation where it will ask if you would like to associate PDF files (and other supported file types) with the PDF viewer app. If you allow the association, the installer will automatically change the default PDF viewer to the app you are installing. In that case, you don’t have to manually change the default PDF viewer in Windows 11.

2. In the “Set a default for a file type or link type” search box, type “.pdf” to search for the file type. Note: The dot (.) in front of “pdf” is required, otherwise you won’t get any result. The current default app for PDF will show up. For example, if the current default PDF viewer is Edge, it will show up as “Microsoft Edge PDF Document”. To change the default to a different app, select the current default app for PDF document.
