PDF Overlay-Set beautifully background for PDF files

Do you guys have any good solution to add background for PDF files then add some password for the designed PDF file? The situation is that I need to write a very sweet letter to my girl friend as a birthday present. But I need to use set her birthday date as the password. Can you guys help you me in this matter? If you can, that would be so so so sweet?”

We have a wonderful software which can help this friend rub the lamp. It is VeryPDF PDF Toolbox Command Line. Mainly, it can merge, split, encrypt, fill PDF form, edit PDF description information, and optimize PDF. For doing PDF Overlay, it is just a pieces of cake for it.  Now let us figure this matter out roughly from the principle. Maybe you have chosen some very beautiful PDF background or images and have written some  mellifluous words to express love for your girl for girl friend. The most difficult part for you to handle is how to put them together. Now let us check the detail solution in the following part.

  • Free downloading software PDF Toolbox Command Line.
  • Unzip it to your PC then you can call it from MS Windows.
  • Check its usage. In this operation, we mainly use PDF Overlay function.

     -overlay : use a specified PDF page as a watermark and put it over the input PDF pages

  • According to the usage, you need to input the command line: pdftoolbox.exe input.pdf –overlay background.pdf –outfile  output.pdf

This command line is for doing PDF Overlay. If you need to add password for it, you need to add other parameters for it. The command line needs to be inputted like this: pdftoolbox.exe input.pdf –overlay background.pdf –outfile  output.pdf  -userpassword  0625

By this way, theoretically you can do PDF Overlay and add password for the designed PDF file. Now let us put them into practice and check the effect. I will take a random background and random poet for example.

First, check the background PDF file from the following snapshot. If you choose the beautiful image file, you can convert image2pdf.

    1. Thanks for your message, pdfstamp.exe hasn’t an option to overlay a text file to the pdf pages, however, we suggest you may convert the text file to PDF file first, then you can use our PDF Toolbox Command Line to overlay this PDF file to existing PDF file, please refer to following web pages for more information,


      You can use our text to pdf converter to convert text files to PDF files,
