Preview PDF Files

Two of the key components of the PDF workflow are: the ability to exchange PDF documents with peers and colleagues, and the administrative flexibility of digital files over paper documents. In both cases, it is not always intuitive to understand what files are being processed based on the filename alone. To simplify the visual management of PDF files,Nitro Pro integrates its PDF viewing engine into Microsoft Outlook and Windows Explorer, allowing you to view your PDF files and attachments before opening them in Nitro Pro.

NOTE: To use the following preview and icon features, you need to set Nitro Pro as your default PDF viewer.

Preview a PDF attachment in Microsoft Outlook

When installed on Microsoft Windows Vista or later, Nitro Pro automatically integrates into Microsoft Outlook (version 2007 onwards) to enable a visual preview of a PDF file contained in an email as an attachment.

Preview a PDF file in Windows Explorer

Just as we previewed a PDF attachment in an email, it is possible to preview the content of a PDF document in Windows Explorer when Nitro Pro is installed on Windows Vista or later.

Icons associated with PDF files in the main pane of Windows Explorer show a preview of the PDF file, which is based on the first page of the PDF document.

This icon preview also applies to the icon in the summary pane at the bottom of the Windows Explorer window.

TIP: You can specify the size of file icons in the View menu. Windows does not apply previews to small icons if you select Small icons, List or Details.
