PDF Page Range Syntax
Separate ranges with commas: 1-3 means pages 1 through 3, 5 means page 5, and 1-3,5 selects those four pages. Ranges cannot be reversed or exceed the total; output follows input order.
1-3: first three pages.
1,3,5: pages 1, 3 and 5.
2-4,7: pages 2-4 plus page 7.
Output page count should equal selected pages.
Check front/back and rotation for scans.
