Hi,

In Python, you have a free PDF library (PyPDF2) for:

·        extracting document information (title, author, …)

·        splitting documents page by page

·        merging documents page by page

·        cropping pages

·        merging multiple pages into a single page

·        encrypting and decrypting PDF files

·        and more!

For VB Script you need to use a library that supports actions on PDF files.

Here are some libraries to work with PDF files:

·        iTextSharp

·        PDFTron

·        DynamicPDF

·        PDFSharp

You also can create your own VB/.Net Plugin to do different manipulations on  PDFs.
