How it works
The tool rearranges the pages of a PDF onto sheets that you print on both sides and fold down the middle, so you end up with a booklet whose pages are in the right order. Each sheet carries four pages: two on each side.
Step by step
-
Upload your PDF
Choose the file or drag it onto the tool. It is opened inside your browser only and is never sent to a server.
-
Choose the book direction
“English” for books that open from the left, “Arabic” for books that open from the right. The wrong choice reverses the page order after folding.
-
Set the options
Paper size, continuous page numbers if you want them, and signatures for thick books. The preview shows where every page lands on every sheet before you download.
-
Choose how you print and download
If your printer prints on both sides you get one file. If not, choose “One side at a time” and you get two files: front sides, then back sides.
-
Print, fold and staple
Print double-sided with flip on short edge at 100% scale, then fold the sheets together down the middle and staple on the fold. Details in the printing guide.
How the pages land on the sheets
Example: an 8-page English book needs two sheets. The first sheet carries the cover (page 1) and the last page on its front, and pages 2 and 7 on its back. The second sheet carries the four middle pages.
Sheet 1
Sheet 2
After printing, put the second sheet inside the first and fold them together: the pages read 1 to 8 in order. The dashed line is the fold.
Because each sheet carries four pages, the page count is rounded up to a multiple of four and blank pages are added at the end of the book. For example, a 13-page file becomes 16 pages on 4 sheets, with 3 blank pages at the end.
