The trial version puts an automatic watermark on all your documents.
Universal Document Converter is a simple tool that lets you convert a written document to a PDF or image. It is compatible with the following formats: TIFF, JPEG, PNG, PCX, DCX, GIF, and BMP.
Once installed, you have to go to the printer's panel of printers and select 'universal document converter' instead of your normal printer. From there, you can modify different options and select the output format.
You can set up a document password or add a watermark. In this way, you can be sure that no one can take credit for your work or use it without your permission.
Universal Document Converter is one of the many conversion tools currently available. So, when it's comfortable, lightweight, and works well, it does not stand quite a lot, is not it.
