N-up printing arranges multiple PDF pages onto a single printed sheet. 2-up puts two pages side by side on a landscape sheet; 4-up fits four pages in a 2×2 grid. It is the standard technique for printing handouts, drafts, and review copies where paper economy matters more than full-size legibility.
When to use N-up
Handouts: a 40-page slide deck becomes a 10-page printout at 4-up, which is far easier to hand out and still readable for most presentation content.
Proofreading: 2-up printing at half size lets you scan pages quickly when you are reviewing for structure and flow rather than fine detail.
Booklet printing: 2-up with a specific page ordering can produce a saddle-stitched booklet — pages printed so that folding the sheets in half produces a correctly ordered booklet.
What the output looks like
Each output sheet contains two or four scaled-down pages from the input PDF, arranged left-to-right and top-to-bottom. The pages are scaled proportionally to fit within the sheet, with a small margin between them. The result is a PDF you can send directly to a printer.
The tool runs entirely in your browser — your PDF is never uploaded. Processing is immediate.
When N-up printing makes sense
N-up printing is most useful when you are printing a PDF for reference rather than for distribution. Presentation slides are the most common case: a 60-slide deck at one slide per page consumes 15 sheets, but 4-up (four slides per page) fits the same deck on four sheets. This is the standard layout used by LibreOffice Impress and PowerPoint's handout print mode.
Other common uses: reducing a long reference document to half the paper for review, printing form pages two-up for easier comparison, or producing double-sided folded booklets from single-sided pages.
How it works
The N-up PDF tool arranges your PDF pages in a grid on each output sheet. For 2-up, two original pages appear side by side on each output page. For 4-up, four pages appear in a 2x2 grid. The output page size is A4 or US Letter, and the original pages are scaled down to fit. The content is vector-rendered, not rasterised, so text stays crisp at any zoom level.
Page order follows reading order: left to right, then top to bottom. For a 4-up layout, page 1 appears top-left, page 2 top-right, page 3 bottom-left, page 4 bottom-right. This matches the reading pattern of most printed handouts.
On-device processing
The N-up PDF tool runs entirely in your browser. The page rearrangement happens locally using pdf-lib. The file is never uploaded. The output is a new PDF with the original pages arranged at reduced scale on the new page grid.
