Pages are copied out of your original file exactly as they are, so an arrangement costs
nothing in quality: text stays searchable, vectors stay sharp, images keep their own resolution.
Drag a page where it belongs
Pick a page up and a blue marker shows where it will land. It works the same with a finger as with a mouse. The number under each page is its place in the file you are about to save, so it renumbers itself the moment anything moves.
Move a whole run at once
Select several pages and drag any one of them: the rest travel with it and keep their own internal order. For longer journeys the arrows move a selection one place at a time, or all the way to the front or the end.
Insert another PDF anywhere
Insert PDF reads a second document and puts its pages in right after the selection — not at the end, which is what merging would do. Dropping a file onto the page area does the same thing.
Every source keeps a colour
Each open file carries a colour, shown beside its name and as a small bar under every page it contributed. Once two documents are shuffled together that colour is the only thing that says which page came from where.
Remove without touching the original
Removing takes pages out of what will be saved. Your files on disk are never opened for writing, so whatever happens here they cannot be damaged. Undo covers eighty steps of arranging.
Opens big documents immediately
Thumbnails are drawn only as they scroll into view, and the cache that holds them is capped, so a 200-page file does not sit on hundreds of megabytes of pictures you are no longer looking at.
