How to Print a Booklet
After downloading the booklet PDF: (1) Open in Adobe Reader or Chrome. (2) Print with "Both sides" / duplex enabled, flipping on the short edge. (3) Stack all printed sheets together. (4) Fold in half. (5) Staple along the fold โ your booklet is ready!
This tool rearranges your PDF pages into booklet order (called "imposition"). For a 4-page document, the booklet order is: Page 4 + Page 1 on Sheet 1 front, Page 2 + Page 3 on Sheet 1 back. Blank pages are automatically added if the total page count is not a multiple of 4.
All processing happens entirely in your browser using PDF.js and jsPDF. Your PDF is never uploaded to any server.
Frequently Asked Questions
Why do I need a multiple of 4 pages?+
Each sheet of paper has 2 sides, and each side holds 2 booklet pages (left + right). So 1 sheet = 4 booklet pages. If your PDF has 10 pages, 2 blank pages are added to make it 12 (3 sheets ร 4 pages).
What printer setting should I use?+
Select "Two-sided printing" (duplex) with "Flip on Short Edge" (also called "Short Edge Binding"). Do NOT select "Fit to Page" โ print at actual size (100%). Page scaling must be off.
Can I make A5 booklets from A4 paper?+
Yes โ this is the primary use case. Two A5 pages are placed side-by-side on each A4 sheet. After duplex printing and folding on the long edge, you get a proper A5 booklet.
Is there a page limit?+
50MB file size limit. Page count is unlimited but very large PDFs (100+ pages) may take a minute to process depending on your device. The progress bar shows conversion status.
Why does my booklet look wrong?+
Check: (1) Duplex printing enabled with "Short Edge Flip". (2) No page scaling โ print at 100%. (3) Correct paper size selected (A4 for A5 booklet). (4) Pages stacked in order before folding.
