Day-to-day scenario
Small businesses forward “all invoices in one scan.” You want separate files named by period without rescanning.
Split PDF into files
Set pages per chunk, download the ZIP, and attach each piece to the right bill or folder. Works best when layout is uniform. Use the output filename pattern (placeholders such as page range or chunk index) so files sort sensibly in shared drives—see Bulk-split with smart file names.
Tip
If only some pages belong together, Extract PDF pages or Reorder PDF pages may be faster than blind chunking.
