I suggest you go with the OSTtoPSTAPP PDF Split Tool. This tool is specially made for it. It can simply support bulk PDF splitting and does not affect the quality or format of the PDF. Just upload all your PDFs and split them in one click. It is very quick and secure and has no PDF file size limit. It also saves the original file in a backup folder. It is suitable for all users and Windows versions. Try the demo application.
