How Do I Split a PDF Using a batch Procedure?

I deal with this exact problem every month when I need to separate client invoices from master PDFs. The batch splitting process took me forever to figure out because most online tools limit you to five files unless you pay. What finally worked was using a Python script with PyPDF2 – it processes hundreds of pages in seconds and gives you complete control over naming conventions. I split by chapter markers or page ranges depending on what I need that day. The trick is testing the script on a copy first because once you split, reassembling takes even more time. After splitting, I use the fax app to send different sections to different departments without rescanning anything. The confirmation reports show exactly when each document arrived, which saves me from those “did you get my email” follow-up calls. I also found that adding date stamps to filenames helps me track which version went where. Batch splitting with proper automation has cut my document preparation time by more than half.
