Imposed on your device — never uploaded
Two related jobs. N-up puts several pages on one sheet — halving or quartering your paper for handouts and drafts. Booklet mode is the harder one: it reorders pages so that when you print double-sided, fold the stack in half and staple the spine, the pages read in order. That reordering is genuinely unintuitive, which is why it is worth automating.

How to use the PDF Booklet & N-up

Why use this tool
Because a 40-page draft becomes 10 sheets at 4-up, and because working out booklet page order by hand is a genuinely error-prone job.
Frequently asked questions
How do I print the booklet correctly?
Print double-sided, flipping on the SHORT edge. Then fold the whole stack in half and staple the fold. If your printer only does single-sided, print the odd sheets, reinsert them, and print the even sheets. Test with 4 pages before committing a long document — the flip-edge setting is the usual culprit when it comes out wrong.
Why did my booklet gain blank pages?
Booklets must have a page count that is a multiple of 4, because each folded sheet carries four pages. A 6-page document is padded to 8 with two blanks, which are placed at the end where they belong.
Are my PDFs uploaded to a server?
No. The file is read with FileReader, processed by pdf-lib inside your browser tab, and written back out as a download. There are no network requests. You can verify this yourself: open your browser's developer tools, go to the Network tab, and run the tool — you will see the library load once from a CDN and nothing else. This matters because the documents people organise are bank statements, ID scans and signed contracts.
Will N-up make the text too small to read?
2-up on A4 gives you roughly A5 per page, which is comfortable. 4-up is fine for slides and drafts. 9-up is really for thumbnails and overview — treat it as a contact sheet, not something to read.
