PrimoPDF is a freeware program that creates a PDF file from Microsoft Windows documents. It works as a virtual printer. It does not present the user with advertisements.[1] But does utilize the OpenCandy Adware program and per its terms of service, may use OpenCandy to recommend other software to the user.[2][3] PrimoPDF is developed by the same company that develops the commercial Nitro PDF software.

PrimoPDF requires the Microsoft .NET Framework 2.0. When the program runs, it tries to download automatic updates from each time it prints. This feature can be disabled within the program settings. It uses the Ghostscript file format converter and RedMon printer redirection software.[4]

According to its documentation, PrimoPDF has the following features:

  • Consistent PDF creation. Use PrimoPDF's creation profiles to produce the same kind of PDF file every time. Profiles include Screen, eBook, Print, Prepress, and Custom.
  • Append PDF files. Combine each newly created PDF file into the one PDF.
  • Secure PDF. Protect and encrypt your information with strong password-based PDF security.
  • PDF metadata. Set the document properties information fields, -- including author, title, subject, and keywords—to index your PDF files and make them easier to search.
  • PDF versions. Create different version PDF files: 1.2, 1.3, 1.4, and 1.5

The software includes ads in the program, so cannot be classified as adware, but uses OpenCandy to supply those ads. OpenCandy includes spyware.
