Conversion of jng files to pdf file format

Any picture or vector image can be printed as PDF document. You just need to find a viewer with print function and use a virtual PDF printer to print in file instead on paper. Another option would be to use some of the dedicated picture conversion programs or online services. So it should be very possible to convert JPEG Network graphics files (.jng) as PDF documents.
