This can be done easily in many ways. Press the "Add File" button to add select one or more PDF Documents, or press the "Add Folder" button to select an entire Folder and add all the PDF Documents that are in this folder.
Alternatively, you can simply right click on the PDF Documents in Windows Explorer and select "Extract PDF Images". In order to do this, you should have selected the option "Integrate with Windows Explorer" during the installation.
Another easy way to add PDF Documents is to drag and drop them on the application window.
