How to split a PDF into separate files
- Tap Choose a PDF to split and pick the document.
- Leave it at one page per file, set a chunk size, or name the pages to cut before.
- Tap Split PDF and wait for the parts to be listed.
- Save them — each is your file’s own name with part-01, part-02 and so on after it.
Three ways to cut, and which one you want
One file per page is the starting point because it is what portals force on you: a form that wants each certificate uploaded separately does not care that they were scanned in one pass. Fixed chunks suit a report or a book — every four pages, say. Cutting before named pages is for a document with an obvious seam, like a statement covering three months.
Pages are never redrawn. Each part is a new document holding the original pages exactly as they were, so text stays selectable and a scan does not lose a generation of quality on the way out.
Why the parts can add up to more than the original
A two-megabyte PDF can split into forty files totalling far more than two megabytes, and it surprises enough people to be worth explaining. When several pages share one scanned image — a letterhead, a background, a stamp — the original stores that image once. Give each of those pages its own file and each file needs its own copy.
The same thing happens on a smaller scale with embedded fonts and with the index every PDF has to carry. This page measures the parts after the split and tells you when they grew substantially, which is better than finding out from your storage.
