Book Binder is a browser-based tool that converts PDFs into printable booklets and binding signatures. It automatically rearranges pages so they print in the correct order for folding, stacking, and binding. No uploads, no installs, no accounts. Files never leave your browser.
Built for Book Binders, zine makers, print shops, and anyone assembling physical documents, Book Binder simplifies imposition—the process of laying out pages so they appear correctly after printing and folding.
Why Book Binder Exists
Most “print booklet” options in standard PDF viewers are limited. They usually:
- restrict sheet counts
- don’t support custom signatures
- fail with odd page totals
- ignore rotation needs
- lack preview accuracy
Book Binder fixes those gaps by giving precise control over sheet layout, signature size, rotation, and scaling.

Help / FAQ
Do you store uploaded files?
No. Processing happens entirely in your browser.
What signature size should I use?
16 sheets per signature is a common default. Larger signatures reduce sewing but increase bulk.
When should I enable alternate rotation?
Enable it when duplex printing flips pages on the wrong edge.
Why do some pages look rotated in preview?
They are rotated intentionally so they appear upright after folding.
What if my page count isn’t divisible by signature size?
Book Binder automatically balances signatures to minimize blanks.
Does it work offline?
If the page is already loaded, yes.
Technical Notes

Summary
Book Binder is a focused utility solving one problem well: turning digital pages into physically printable book structures. It’s fast, private, configurable, and built specifically for real bookbinding workflows rather than generic print layouts.
