Reorder and impose the pages of a PDF so you can print, fold in half and staple it as a booklet.
The body is always padded with blank pages to a multiple of 4 (needed for folding). To simply arrange several pages per sheet without booklet sequencing (no folding), use "Prepare for printing".
Choose the document you want to turn into a folded booklet.
Set the final page size and the binding type (folded in half), so the tool knows how to reorder the pages.
The resulting PDF has its pages rearranged (imposed) so that, once printed double-sided and folded in half, they're in the correct reading order.
It's the technique of reordering a document's pages (for example, placing the last page next to the first) so that, once printed on larger paper and folded, the pages appear in the right sequence when you leaf through the booklet.
Usually yes, for a simple booklet folded in half — if your document's page count isn't a multiple of 4, the tool can automatically add blank pages to make it up.
Print the resulting PDF double-sided (duplex), flipping on the short edge, so the pages line up correctly once folded.
