The plan preview and review package are not production validation. A production decision requires the exact canonical output receipt, semantic placement proof, post-imposition preflight, and release policy together.
This process preserves the original design elements of your document (such as colors, fonts, and transparency) without making any destructive alterations.

Get print quotesHow booklet imposition works
In a saddle-stitch booklet, pages fold into signatures: on an 8-page job the outer sheet carries pages 8 and 1 on its front, 2 and 7 on its back. Our engine plans that ordering, the duplex alignment and, if you ask, paper-thickness compensation (creep) in exact integer arithmetic. The receipt binds the output to that structural plan; measured render evidence is reported separately when it is available.
How to impose a booklet, step by step
Open your PDF
Drop the file on this page. It is read inside your browser — nothing is uploaded and no account is created.
Check binding and template
The saddle-stitch booklet template is preselected. If your page count is not a multiple of four, the plan pads it with blank pages — a 22-page file becomes a 24-page booklet.
Create the plan
The engine computes signatures, page order and front/back alignment in exact integer arithmetic, and shows how many sheets and sides the job takes.
Generate and download
The imposed PDF is composed in your browser and downloaded. Every output carries a receipt with an integrity check and the result of a measured local check.
Frequently asked questions
- How many sheets does a booklet take?
- A saddle-stitch booklet puts four pages on every sheet: two on the front, two on the back. So 16 pages need 4 sheets and 32 pages need 8. A page count that is not a multiple of four is padded with blank pages first — a 22-page file becomes a 24-page booklet on 6 sheets.
- How are booklet pages ordered?
- Pages pair from the outside in: on an 8-page booklet the outer sheet's front carries pages 8 and 1, its back carries 2 and 7. The tool computes this ordering for any supported length, so you never sort pages by hand.
- What is creep, and when do I need it?
- In thicker booklets the inner sheets bulge outward at the fold, pushing inner-page content toward the trim edge. Creep compensation shifts content inward by the paper's thickness per sheet. Over a handful of sheets it is barely visible; on 40+ pages or heavier stock it keeps margins even after trimming.
- Is my PDF uploaded to a server?
- No. The file is opened and imposed entirely inside your browser: no bytes leave your device and no account is needed. This is enforced by the page’s data path, not merely promised in words.
