Open a PDF in App from SharePoint

[davidpoon]

You know how you can choose to open a Word or Excel Doc in SharePoint either In Browser or In App? I'll like to open a PDF file In App (using Adobe PDF) from SharePoint. What am I missing? Why isn't there an option like for Word or Excel?

AFAIK, PDF can only be opened in the browser

This is the 2nd most requested feature for SharePoint. See https://feedbackportal.microsoft.com/feedback/idea/42d81285-dd1c-ec11-b6e7-0022481f8046

The OOTB viewer shows the pdf file in the browser (as read-only). In many case there is also a need to annotate or sign the pdf file. This requires 3rd party Apps. Some use the pdf capabilities of modern browsers (only viewing though), others use local client installs (view and modify).
