As you already know, within a PDF file you can add what is called a break point, meaning a separator within the PDF itself. So, if you have a large PDF that contains these breaks and you want to divide it into smaller PDFs, then you need A-PDF Manual Split.
The mission of A-PDF Manual Split is very simple: it creates new PDF files from the break points it finds; thus you`ll have as many PDF files as there are breaks in the original PDF.
The whole process in A-PDF Manual Split is automated, allowing you to save a lot of time and effort not having to do it manually.
