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.
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.
