Practical use cases
- A scanned textbook or report where each chapter is the same number of pages — split it "every N pages" to get one file per chapter in a single pass.
- A stack of documents scanned together as one PDF (receipts, forms, ID cards) where every page is really its own document — auto-split "one page per file" separates them instantly.
- Pulling out a specific, non-contiguous set of pages — say pages 2, 5, and 9 of a report — to send as one combined file using manual mode.
How page ranges are separated
In manual mode, the pages you select come out as a single new PDF, always in ascending page order (regardless of the order you clicked them) — the original file is untouched. In auto mode, PDFDistrict calculates every chunk in advance and shows it in the preview before you click Split; each chunk then downloads as its own separate file, one after another. Because several files can download in quick succession, your browser may show a one-time prompt asking to allow multiple downloads from this site — that's your browser's own download manager, not something PDFDistrict controls.
Common problems
- Nothing happens when you click Split in manual mode: that means no page is marked yet — the message "Select at least one page first" is the tell.
- Auto mode won't calculate chunks: "Could not calculate page ranges. Check your settings" appears if the numbers entered (pages per split, or number of parts) don't make sense for the document — e.g. more parts than pages.
- Only one file downloaded when you expected several: check which tab is active — manual mode always produces one file; auto mode produces multiple.
