Visual page organization explained
Organize mode shows each page as a thumbnail you can drag to a new index. Deleting removes a page from the output document entirely. The saved PDF contains only the pages you kept, in the order shown in the grid.
Unlike merge, organize works on a single source file. Unlike split, it produces one output rather than many. Think of it as editorial control over page sequence inside one document boundary.
Underlying implementation copies retained pages into a fresh PDF in the chosen order. Removed pages never appear in the output binary, which can reduce file size when you drop heavy scans you no longer need.
Organize mode complements merge: fix order inside a combined file without returning to separate sources scattered on disk.
Deleted pages free file size proportionally when removed content included heavy images—organize doubles as lightweight cleanup before compression.
