What it does
Printing pages 1, 2, 3 in order does not give you a booklet. For a folded booklet each sheet must carry pages from both ends of the document, such as 8 and 1 on one side and 2 and 7 on the back. This tool rearranges your PDF into that order, two pages per landscape side, so you can print double-sided, fold the stack in half and staple the fold.
It also puts 2 or 4 pages on each sheet in normal reading order to save paper, and it can enlarge one page over a grid of sheets as a poster, with overlap and cut marks for taping. Number the pages first with page numbers, and reorder or remove pages with organise PDF before you start.
How to use it
- Choose a PDF. The page count shows.
- Pick Booklet, Several pages per sheet, or Poster.
- Set the paper size and the options for that mode.
- Press Make PDF, then print the result at 100% (not “fit to page”).
What each setting does
- Booklet, flips on: choose long edge for most printers. Pick short edge if the back sides come out upside down.
- Pages per sheet: 2 (landscape) or 4 (2 by 2). A thin border can mark each page.
- Poster: the page to enlarge, sheets across and down, overlap in millimetres, and cut marks at the printable corners. Each sheet is labelled with its row and column.
Worked example
A 6-page PDF is padded with 2 blank pages to 8. That makes 2 sheets, or 4 printed sides: side 1 has the blank and page 1, side 2 has pages 2 and a blank, side 3 has pages 6 and 3, and side 4 has pages 4 and 5. Fold the two sheets together and the pages read 1 to 6.
FAQs
Why are there blank pages at the end? A booklet needs a multiple of four pages. The blanks go at the back.
My back sides are upside down. Switch “flips on” to the other edge and make the PDF again.
Will rotated pages work? Pages that are stored rotated may sit sideways. Fix them first with the organise tool.
Is my PDF uploaded? No, it is rearranged in your browser.
Where the numbers come from
- The booklet order is the standard saddle-stitch layout: each sheet carries four pages, so the page count is padded to a multiple of four with blanks. Paper sizes are ISO A4 (210 x 297 mm) and US Letter (8.5 x 11 in).
Standard scientific values, such as constants, atomic weights and melting points, are facts found in every textbook; we name where ours were checked. If you are an author or publisher and want a value, a credit or a table changed or removed, tell us and we will act quickly.
