From the same author as the PDFConcat program, now comes this tool called PdfExtract, which could be defined as a utility that does the opposite.
Well, the objective of PdfExtract is to extract from a PDF or PS file the pages it contains, being able to save each of them as independent PDFs. In this way you do not need to have the entire PDF but only the pages that interest you most. It is also a frontend for GhostScript.
NOTE: For its correct operation you need to have previously installed Microsoft.NET Framework 1.1 or higher.
You can free download PdfExtract 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
