What this does
A booklet imposes the pages so that a stack of double-sided sheets, folded down the middle and stapled, reads in order. That means page one shares a sheet with the last page, page two with the second to last, and so on — arithmetic that is easy to get wrong by hand and impossible to check until it is printed. Blank pages are added at the end where the count is not a multiple of four.
What it will not do
Every tool here says what it cannot do, in its own words, before you rely on it.
- The sheets come out in printing order. Feed them through as one stack, then fold and staple.
- A bookmark follows its page to the sheet it landed on. Links and form fields do not: two pages now share a sheet, and there is nowhere correct to put them.
- The booklet reads left to right.
Questions people ask
How do I print the result?
Print it double-sided, flipping on the short edge, as one stack. Then fold the stack down the middle and staple through the fold.
What if my document is not a multiple of four pages?
Blank pages are added at the end to make it one, because a folded sheet always carries four pages. A nine-page document becomes twelve, with three blanks at the back.
Is my file uploaded anywhere?
No. The work happens in this browser tab, on your own machine. There is no server in this product to send a file to, which is why the promise is checkable rather than something you have to take on trust: open your browser's network panel and watch it do the work without making a request.
Is there a size limit, or a limit on how many files?
None that we impose. The limit is your own machine's memory, because that is where the work happens — a few hundred megabytes is comfortable on a laptop, and less on a phone. There is no daily task counter, no queue and no account.
What does it cost, and what is the catch?
Nothing, and there is no paid tier that unlocks features: the whole product is the free one. That is affordable because running it costs us nothing — your computer does the work — so there is no per-file cost to recover, no advertising and no data to sell.
