Real booklet imposition, instantly
Your pages are reordered into true saddle-stitch booklet order: two pages per side, so folded sheets read in sequence. All in your browser.
How it works: page count is padded to a multiple of 4, then pages are paired sheet by sheet (for example a 12-page PDF becomes sheets 12|1, 2|11, 10|3, 4|9, 8|5, 6|7). Print double-sided flipping on the long edge, fold, staple, done.

Frequently asked questions
How does booklet imposition work?
Your page count is padded to a multiple of 4, then pages are paired sheet by sheet (for example a 12-page PDF becomes sheets 12|1, 2|11, 10|3, 4|9, 8|5, 6|7). Each sheet is a landscape page with two original pages side by side.
How do I print the booklet PDF?
Print double-sided with the flip on the long edge, then fold the stack in half and staple along the spine (saddle-stitch). Pages will read in the correct order.
Is my PDF uploaded anywhere?
No. The imposition uses pdf-lib entirely in your browser. Your document never leaves your device.
