<p>By default, Chrome uses a built-in PDF viewer to open PDFs. If you've disabled the built-in PDF viewer, Chrome will use Adobe Acrobat or Adobe Reader to display PDFs. Follow the suggestions below if you're having trouble viewing PDFs within Chrome, using Adobe Acrobat or Adobe Reader. First check if the issue is specific to Chrome. Try opening PDFs in another browser on your computer, such as Firefox. If you experience similar problems viewing PDFs in another browser, the issue is likely not related to Chrome. Please visit the Adobe support site for additional help.</p><p>Adobe Instructions</p><p>Follow the instructions below to confirm that either Adobe Reader or Adobe Acrobat is configured to display PDFs in the browser.</p><p>Only one of the programs should be set to preview PDFs in the browser, not both.</p><p>1.
