Display PDF in browser

Acrobat DC, Acrobat Reader DC

You can open PDFs on a web page either within your web browser or in Acrobat or Reader. Find instructions specific to each browser below.

Note: Each browser has its own settings to control how PDFs open from a web page. Acrobat DC and Acrobat Reader DC do not include a preference setting to open web-based PDFs. To change the display behavior, follow the instructions below for your browser, or see the browser documentation on how to control plug-ins or add-ons.

You must have root user privileges to change Safari plug-ins. To display PDFs using the Safari PDF viewer, you must disable the Adobe PDF Viewer.

Quit Safari.
Log in as the root user. The root user privileges aren't enabled by default because the root user can change system files.
Choose Go > Go To Folder.
Type /Library in the Go to the Folder field, and click Go
Create a new folder in the Library folder, and name it Internet Plug-ins Disabled.
Open the Internet Plug-ins folder, and move both the AdobePDFViewer.plugin and the AdobePDFViewerNPAPI.plugin into the new Internet Plug-ins Disabled folder.

Note: If both AdobePDFViewer plug-ins are still in the Internet Plug-ins folder, drag them now to the trash. You may be asked for your name and password.
