How to Print a PDF as a Booklet

Printing a PDF’s pages in their normal order and folding the stack in half doesn’t produce a readable booklet — the pages land in the wrong spots. Booklets need “imposition”: a specific rearrangement so the fold lines everything up correctly.

Steps

1. Drop your PDF above.
2. Click Make booklet.
3. Print the result double-sided, flipping on the short edge, then fold the whole stack in half.

Why the order looks scrambled

The tool reorders your pages into saddle-stitch sequence — pairing the last page with the first, the second with the second-to-last, and so on — and lays two of them onto each landscape sheet. That looks wrong on screen, but it’s exactly what’s needed: once the printed stack is folded down the middle and stapled along the spine, the pages read 1, 2, 3, in normal order. If your page count isn’t already a multiple of four, blank pages are appended at the end automatically, since a folded booklet needs the total to divide evenly into four.

Notes

This assumes your source pages are all a consistent size. Everything runs locally, so nothing is uploaded. If you want multiple pages per sheet without the fold-order rearrangement — for a handout rather than a booklet — use N-Up instead. For reordering or resizing pages before you build the booklet, see Organize PDF.
