FAQ

Are my PDFs uploaded to a server?

No. Booklet imposition runs entirely in your browser using JavaScript and pdf-lib. Your files never leave your device, and the tool works offline.

What booklet types are supported?

Three: (1) Saddle-stitch — fold sheets in half and staple through the spine, ideal for 8-64 page booklets. (2) Perfect-bound — group pages into signatures, then bind with glue along the spine, ideal for thicker books. (3) Gate-fold — 3 panels per side (6 pages per sheet) for tri-fold brochures and booklets.

How is the page order calculated for saddle-stitch?

For a booklet of N pages (multiple of 4), sheet i has: front=[N-2i, 2i+1], back=[2i+2, N-2i-1]. When sheets are nested and folded, pages read sequentially from 1 to N. The tool pads blank pages automatically if your page count isn't a multiple of 4.
