How the booklet tool works
Three steps from a linear PDF to a print-ready saddle-stitch spread sheet.
Upload your PDF
Drop in your linear, front-to-back page order — page 1 through the last page, just as you designed it.
Pick saddle stitch
The tool nests your pages into signatures and reorders them into printer's spreads for duplex output.
Print, fold, staple
Download the imposed PDF, print duplex, fold at the center, and staple through the spine.
Built for short-run booklets
Honest capabilities, no vague promises.
Automatic page nesting
Reorders any page count into correct saddle-stitch signature spreads, including odd counts.
Duplex-ready spreads
Output is arranged for double-sided printing so front and back land in register when folded.
Runs in your browser
Client-side processing means your file is handled locally without a mandatory upload step.
Multiple-of-4 warnings
Flags page counts that are not divisible by 4 so you can add blanks before you send it to print.
No account required
Open the tool and impose a file immediately — no login wall between you and your booklet.
Works for zines & programs
Handles the short-run formats saddle stitch is made for: zines, bulletins, lookbooks, event programs.

One folded sheet of paper = 4 pages (front outside, front inside, back inside, back outside). A booklet's total page count must be a multiple of 4 so every sheet nests evenly. See the multiples-of-4 explainer for the full visual breakdown.
Frequently asked questions
What is saddle stitching?
Saddle stitching is a binding method where folded sheets are nested inside one another and joined with two wire staples through the spine fold. It is the standard binding for zines, church bulletins, event programs, and lookbooks up to roughly 60-80 pages, depending on paper weight.
Why does my page count need to be a multiple of 4?
Each saddle-stitch sheet is one piece of paper folded in half, which creates exactly 4 pages (2 front, 2 back). A booklet is built from a stack of these folded sheets, so the total page count must be divisible by 4 or the imposition leaves an unprinted or mismatched page.
How many pages can I safely saddle stitch?
As a rule of thumb, 80gsm text stock works up to about 64-80 pages, 100gsm text works up to about 48-64 pages, and 130gsm stock tops out around 32-40 pages before creep and spring-open force become a problem. Add a heavier cover and the practical limit drops slightly.
Does this tool upload my PDF to a server?
No. The imposition tool linked from this site runs the layout entirely in your browser using client-side processing, so your file does not need to leave your device to be reordered into booklet spreads.
What paper weight should I choose for a zine or lookbook?
For a soft, foldable feel most zine makers use 80-100gsm uncoated text stock for interior pages and a slightly heavier 150-170gsm cover stock. Heavier interior stock looks premium but pushes the page-count ceiling down and increases creep.
Where do I hide blank pages if my count isn't a multiple of 4?
Blank pages are least noticeable at the very end of the booklet, on the inside back cover, or as a deliberate notes page. Avoid inserting a blank in the middle of the sequence, since saddle-stitch signatures print two pages per half-sheet and a mid-book blank breaks the flow of spreads.
Can I use this for church bulletins and event programs?
Yes. Saddle stitching is the standard binding for short-run bulletins, event programs, and lookbooks because it is fast, cheap, and lies flat when opened. The imposition tool arranges your pages into the correct printer's-spread order for duplex printing and folding.
