Music notations from a Guitar Pro 5 project (.gp5) can be printed as a PDF document using the File ► Export function in the program. This is used mainly for printing purposes, so the notations can be shared on paper. You may be able to achieve the same with other music notation software tools, with Guitar Pro formats support but it is unlikely you will find a dedicated gp5 to pdf converter.
