If you are looking for the simplest approach to divide large PDF files into various small files without destroying the file content then I will suggest you use the
MacSonik PDF Splitter for Mac. It gives you an option to save PDF attachments in a sub-folder after splitting. The software provides you with various advanced splitting options like splitting by range, size, after a particular page number, by even page, and by Odd pages. Moreover, the program works with all the editions of Mac OS.
