PDF Watermark Tool

PDF documents are easy to share and transmit. However, in some situation, you have to add watermarks to the PDF and declare the copyright. Here is a tool for adding watermarks to PDF, VeryPDF PDF Watermark Tool.

PDF Watermark Tool is able to add image watermarks to PDF by command line. It has three versions for Windows, Mac OS, and Linux. The functions and options of each version program are the same.

To put the image to PDF using this tool, you have to import the image to a PDF file. Then PDF Watermark Tool can use the image in the PDF as a watermark and add it in another PDF. (For learning how to import image to PDF, please see Image to PDF Converter.)

The following words are about how to add an image in PDF as watermark to another PDF using PDF Watermark Tool of Mac OS version.

Download Mac OS version PDF Watermark Tool and mount the DMG image to your Mac OS system. Then you will see a directory bin where the executable of the tool is. Open a terminal and you can add an PDF as watermark to another PDF by the following commands.

pdftoolbox nml.pdf -underlay img.pdf -outfile watermarked.pdf

In the command line, nml.pdf is the PDF that will be watermarked, and img.pdf is the PDF contains the image that is used as watermark and watermarked.pdf is the name of new created PDF with watermark added. Option -underlay means to put the page of file img.pdf under the pages of nml.pdf, and then save it to watermarked.pdf indicated by -outfile.

The command line above only uses the first page of file img.pdf as watermark and adds it to nml.pdf. If you use option -mulunderlay instead of -underlay, all the pages of img.pdf will be used as watermarks and added to each corresponding numbered page of nml.pdf.

To learn more other options, please input the command pdftoolbox without any arguments or options, then a brief manual will be displayed in the terminal. There are also many runnable examples in the sub directory test.
