There are either GUI version of this software or command line version, so this software can satisfy your all kinds of needs. In the following part, I will show you how to use this software by the command line version.

Step 1. Download PDF Split-Merge Command Line

  • When you need to create a new PDF from a portion of an existing PDF file, please refer to the following command line template.
     pdfpg.exe delete C:\A.pdf,1,3 C:\out.pdf
    pdfpg.exe delete C:\A.pdf,-20,50 C:\out.pdf
    pdfpg.exe delete C:\A.pdf,1,3- C:\out.pdf
    pdfpg.exe delete C:\A.pdf,1,2,3 C:\out.pdf
    pdfpg.exe delete C:\A.pdf,1,1-9 C:\out.pdf
    pdfpg.exe delete C:\A.pdf,even C:\out.pdf
    pdfpg.exe delete C:\A.pdf,odd C:\out.pdf
    You do not need to extract some portion of PDF file by the command line but you need to delete pages that you do not need to keep.  Say by the last command line you can delete all the odd pages from existing PDF file. So by this way, you can also keep that small portion you need in the PDF file. When deleting, you can choose the keep bookmark or not. When deleting pages, those pages could be not continuously, say you can delete pages like 1-20,50.

By this software, you can also merge PDF files from many to one. During the using, if you have any questions, please contact us as soon as possible.
