Merge
Merge several documents into one, with an index of the documents in front, a separator page before each one and bookmarks.
Split
Split a document by groups of pages or every few pages.
Pages
Keep, delete or reorder pages, rotate them, number them, write a watermark across them, or clean the information that identifies where a file came from.
Pages are typed like 1-3, 5, 8- (8- means page 8 to the end).
Each result is kept and listed in the journal.
