Size-driven, not structure-driven
Unlike range splits, size splitting answers a logistics question: "parts under 10MB each". Cuts land at page boundaries closest to the size budget — the document's content decides how many parts result.
Consider compressing first
Often the better first move: compression may bring the whole file under the limit in one piece — split only what compression cannot shrink enough. One document beats three parts when both fit. Files are processed temporarily and deleted automatically — there is no general cloud storage.
