Load one or more PDFs, then drag pages to reorder, rotate, delete, or interleave. Click a thumbnail to confirm it at full size. Everything runs in this tab. Nothing is uploaded anywhere.
Numbers are grid positions (1 = first card), not the page numbers printed on the cards. The highlighted cards are what the buttons will act on.
Rotation is applied on top of whatever rotation the source file already has, so sideways scans come out upright. The interleave and swap shortcuts only activate when exactly two files are loaded. Pages can also be moved with the ◀ and ▶ buttons on each card, or by focusing a card (Tab) and using the arrow keys. While a card is focused: R rotates, Delete removes, Enter opens the full size view.
The page range section works on a block of pages at once, which beats holding Delete on a long document. Start and End are grid positions counting from 1 and both ends are included; the matching cards light up so you can check the selection before acting. Delete and rotate leave every page outside the range untouched. Shift slides the block earlier or later by the given number of positions, and the pages it steps over move to the opposite side of the block, so the rest of the order is preserved. The range follows the block as it moves, so you can keep clicking.
