Short, plain answers about rearranging PDF pages in the browser: how reordering works, what rotating really changes, and what happens to the file you save.

• How to reorder PDF pages

  Why a PDF's page order is rarely the reading order, what actually changes when you move a page, and three ways to put the pages where they belong.

• How to rotate PDF pages

  Why scanned pages come out sideways, what a PDF actually stores when you rotate one, and why rotating the view is not the same as rotating the document.

• How to duplicate a page in a PDF

  When you need the same page twice, what a structural copy is, and why duplicating a page is different from taking a picture of it.

• How to edit PDF pages in bulk

  Selecting pages as a set, applying one action to all of them, and the two behaviours worth expecting from a tool: one undo per action, and order preserved.

• Can you organize PDF pages without uploading?

  The difference between server-side and browser-side PDF tools, how to check which one you are using, and what "stays on your device" does and does not mean.
