Separating chapters from a large PDF is easy if you use the right tool. Doing it manually takes too much time and might break formatting. If your PDF has multiple chapters, you can extract them using a smart splitter tool that gives page range options. The OSTtoPSTAPP PDF Split Tool can help in selecting specific pages or chapters and saving them as new files. Its PDF split tool can easily support so many bulk PDF files in one process, so if you have many documents with chapters, this tool handles them together. You just need to enter the start and end pages of each chapter, and the tool will create a separate file for each one. It can also keep your original PDF file in a backup section, doesn’t lose formatting, and works offline. The tool is very easy to use, even if you’re not a technical person. It supports all Windows OS, Windows 98, XP, Vista, Windows 7/8/8.1, and Windows 10 and 11 (32-bit & 64-bit).
