PDF Multi Watermarker allows you to add a watermark to all of the pages of a PDF document. It will allow you to add up to four separate text and one image watermark. The image watermark may be any image in JPEG, PNG, TIFF, or GIF format. The image may be placed at any one of nine preset places or dragged to any other place on the page. Alternatively the image may be tiled across the whole page.
The watermarks are applied to a copy of the PDF document leaving your original document untouched.
Note: The program is not suitable for use with documents that contain internal links. The minimum screen size is 1280 x 800 pixels.
