Organize PDF tools

Page-level surgery on a document you already have: nothing about the content changes, only which pages exist and what order they sit in. Merge PDF concatenates several files into one; Split PDF does the reverse, cutting a long document into ranges or fixed-size chunks. Extract PDF pages keeps a subset and discards the rest, while Delete PDF pages keeps everything except the pages you name — the same operation approached from opposite ends, so pick whichever list is shorter to type.

Reorder PDF pages and Organize PDF both give you a thumbnail board. Reach for Organize PDF when a single pass needs to reorder, rotate, delete and insert at once, and for the narrower tool when it does not. Rotate PDF fixes pages that were scanned sideways. Crop PDF trims margins to a rectangle you draw, and Halve PDF pages cuts each sheet down the middle — which is how an A3 spread scanned as one page becomes two readable A4 pages.

Rearranging pages is the kind of edit people make to contracts, payslips and medical records: documents you would rather not hand to a stranger's server just to move page 7 in front of page 3. Every tool here loads the file into your browser's memory, rewrites the page tree there, and hands you the result as a download.
