Advanced Bulk PDF Watermark Creator automates the task of stamping one or more PDF documents with a watermark. The application automatically imports all PDF documents from a specific directory and all of its subdirectories. Alternatively, users can manually import PDF documents that need to be stamped with a watermark. For each imported input PDF document the application creates a watermarked copy of the original PDF file. Original PDF documents are not affected by the watermarking process. (Please note that input PDF files may not be password protected and must allow content copying and page extraction.) Advanced Bulk PDF Watermark Creator allows users to define the following watermark properties: single-line verbiage, multiple-line verbiage, font family, font color, font size, font style, rotation / no rotation, placement beneath / above existing PDF content. In addition to this, the application allows users to define multiple-line watermarks with the use of \n line separator and automatically persists most recently used input and output directory paths.
