PDF Booklet Maker

Turn any PDF into a foldable booklet: two pages per side, ordered so that printed double-sided and folded down the middle they read 1, 2, 3… The page count is padded to a multiple of four, and the fold can sit on the right for right-to-left scripts.

A booklet is an ordering problem: the last page belongs beside the first, the second beside the second-to-last. This page does that ordering and lays the pairs on sheets ready for a duplex printer. Everything happens in your browser - nothing is uploaded.

Frequently asked questions

How do I print a PDF as a booklet?

Open the PDF here and save. Then print the result double-sided, flipping on the short edge, and fold the stack down the middle - the pages will read in order.

What if my page count isn't a multiple of four?

It is padded with blank pages at the end, exactly as a printed booklet needs; the preview shows them as dashed cells.

Can the fold be on the right?

Yes - choose "Right (RTL)" for Hebrew, Arabic or any right-to-left book; the pairs are mirrored.

Is the PDF uploaded?

Nothing is uploaded: the file is opened and processed inside your browser and never leaves your device. Close the tab and it is gone.
