Reorder a PDF into print-ready booklet layout — fold and staple the printed result into a finished booklet. Free, in your browser.
🔒 The PDF is processed entirely in your browser — nothing is uploaded.
Handouts, programs, zines, and small reports read better folded into a booklet than as loose stapled-in-the-corner pages. Getting the page order right for that fold by hand is fiddly — page 1 doesn't print next to page 2, it prints next to the very last page — which is exactly the calculation this tool automates.

This tool reorders your document's pages into "imposition" order — the specific, non-obvious sequence that makes a stack of double-sided sheets fold into a booklet with pages in the right reading order. For an 8-page document, that means the printed sheet order is 8-and-1, then 2-and-7, then 6-and-3, then 4-and-5 — not the order you'd guess.
The output is a new PDF, twice the width of your original pages, ready to print double-sided and fold. If your page count isn't already a multiple of 4 (required for even folding), blank pages are added automatically at the end.
How does booklet printing actually work?
Two of your original pages are printed side by side on each side of a larger sheet. When the stack of sheets is folded in half and stapled along the fold (saddle-stitched), the pages land back in the correct reading order — that reordering is exactly what this tool calculates and produces for you.
Is my PDF uploaded to a server?
No. The page reordering and layout is done entirely inside your browser using pdf-lib — the file is never transmitted anywhere.
Does my page count need to be a multiple of 4?
Saddle-stitch booklets are always printed in multiples of 4 pages. If your PDF isn't, the tool automatically adds blank pages at the end to round it up, so you don't need to prepare that yourself.
What printer setting do I need after downloading?
Print the output double-sided, flipping on the short edge, at actual size (not "fit to page"), then fold the whole stack in half at once and staple along the fold. The output file is already laid out in the correct sheet order — no "booklet printing" setting in the print dialog needed.
Will this work for large documents?
Saddle-stitch (fold-and-staple) booklets work best up to roughly 40-60 pages — beyond that, the fold becomes bulky and pages near the middle can creep outward. For longer documents, consider printing in smaller booklet sections.
What page size does the output use?
Each output sheet is twice the width of your original pages (two original pages side by side), so an A4 source produces A3-width output sheets. Print at actual size on the correct paper for it to fold correctly.
