Splitting is how a 200-page scanned bundle becomes the six pages someone actually asked for. Free tools usually cap this exactly where it hurts — Sejda's free tier stops at 50 pages, which is precisely the size of document that needs splitting.
Choose page ranges, split at a fixed interval, or pull out a single chapter. You see the page thumbnails while you choose, so you're not guessing at page numbers — which is the difference between splitting a document once and splitting it three times because pages 40-52 turned out to be pages 41-53.
Ranges accept the notation you'd expect: 1-3, 7, 10- means the first three pages, page seven, and everything from page ten to the end. Splitting at a fixed interval is the one you want for a batch of scanned two-page forms that came through as a single file, and splitting into equal parts is for chopping something oversized into email-sized pieces.
