PDF Booklet Maker — Print & Fold Booklet Imposition, Free

Turn any PDF into a print-and-fold booklet. Automatic saddle-stitch page imposition, signature splitting for long documents, and separate covers — free, runs in your browser.

What it does

Upload a PDF and this tool rearranges its pages into the correct order for booklet printing: pairs of pages placed two-per-sheet so that, once printed double-sided and folded down the middle, the pages read in the right order from front to back. You print the result on a standard printer, fold, and staple — no print shop required.

How it works

The tool uses the standard saddle-stitch imposition sequence — the same page order used by Microsoft Word’s “Book fold” feature and Adobe Acrobat’s booklet print option — where a document is automatically padded to a multiple of four pages, then each physical sheet gets the correct pair of pages on its front and the correct pair on its back. For documents longer than a single comfortable fold (past roughly 40 pages), it can split the pages into separate “signatures” — smaller nested-fold sections, the way real bound books are actually printed — instead of one unwieldy giant fold. Every page’s own rotation is read and corrected automatically so pages that were scanned or saved sideways still come out upright.

How to use it

Add your PDF (or several, which are combined in the order you add them).
Choose a sheet size — match your source pages, A4, Letter, or a custom size.
Set the duplex flip option to match your printer (short edge is the standard default for booklet printing).
For long documents, pick a signature size instead of one giant booklet.
Optionally turn on separate front/back covers, a fold-line guide, or extra blank pages.
Preview the sheet order to double check it, then build and download the imposed PDF.
Print double-sided using the duplex setting you chose, fold each sheet (or signature) in half, and staple along the crease.

Supported options

Signatures: split a long document into fixed-size nested-fold sections instead of one single fold.
Separate covers: print the first and last page as their own full-size sheets rather than imposed two-up, useful when covers go on heavier stock.
Fold guide: a faint dashed line down the center of every sheet to make folding accurate.
Extra blank pages: pad the start or end of the booklet body with blank pages before imposing.

FAQ

Why did my printout come out in the wrong order? This almost always means the duplex flip setting on the print dialog doesn’t match the one selected here. Try switching between “short edge” and “long edge” and reprinting just the first sheet to check.

What does “signature” mean here? In bookbinding, a signature is one folded, nested group of sheets. A single fold works fine for a short document, but folding 25 sheets (100 pages) into one nest gets bulky and the inner pages creep inward. Splitting into signatures of, say, 24 pages each and stacking them keeps each fold thin and the pages properly aligned.

Can I combine several PDFs into one booklet? Yes — add them one at a time and they’re combined in the order you add them, before imposition.

Will bookmarks or links survive? No — imposition fundamentally restructures the page layout, so bookmarks, internal links, and form fields aren’t carried into the output.

Is my document uploaded anywhere? No — everything, including the page rearranging and final PDF generation, happens locally in your browser.
