Win2PDF Pro can overlay an existing PDF file on newly created PDF files (Add a Watermark) or place and existing PDF file behind text and graphics on newly created PDF files (Add a Background). The existing watermark or background PDF file can contain any text or graphics, but it most often used to apply a "confidential" or "draft" stamp on each page of a document. To enable the watermark or background feature, select the "Add a Watermark" or "Add a Background" option in the Win2PDF "PDF Options" dialog.
Add a Background or Watermark
When the watermark or background options are enabled, a text box containing the name of the current watermark or background PDF file is shown below the options. If you would like to change the file, click the "Change..." button and select a new watermark or background PDF file. Win2PDF will always display the last used watermark or background PDF file when the feature is enabled.
If the watermark or background PDF file contains more than one page, only the first page will be applied to each page of the new document. It's best to use a watermark or background PDF file that has the same page size as the newly created PDF file. If the watermark or background file has a different page size, it will be scaled and centered on the page of the newly created PDF file.
You can create the watermark or background PDF file using Win2PDF and any Windows application such as Microsoft Word. If you are using Win2PDF Pro, the watermark or background PDF file must not be encrypted. Some sample watermark and background PDF files and the corresponding Word documents are available on the download section of the support web site at:
