Weeny Free PDF Merger 1.3

Weeny Free PDF Merger is an application which helps you merge PDF files. Besides this main function, this tool has the ability to add watermarks and set passwords to the output document.
The installation of the program doesn't take long. Yet, you need to pay very much attention to the wizard guide; otherwise, you get yourself with unwanted programs that disturb the proper function of your computer. The interface is nice and simple. It provides only few buttons, which are suggestively entitled. Once the PDFs are selected, they are brought to the list pane with some basic information, such as the size and the number of pages of each document. If the source files are password-protected, then a new window pops up automatically asking you to fill in the password required for opening the document.

An additional feature provided by this tool is an ability to add a watermark to the target file. The watermark may be a text or an image which can be customized in terms of opacity and font size. You can also rotate it and place it wherever you want in your document.

Apart from the above-mentioned options, the program allows you to set passwords to the target file. I refer to either a user password necessary for opening the document, or a master password to restrict editing and printing.

All this being mentioned, my conclusion is that the application functions well, with no errors encountered while testing it. However, I would like to view the source files within a preview window; thus, I would make sure that I selected the right files for the conversion.
