TL;DR: Upload a PDF and download an n-up version that fits 2/4/6/8 logical pages onto one physical page — saves paper when printing.
Print multiple PDF pages per sheet online — arrange 2, 4, 6, or 9 pages onto a single sheet for booklet-style printing. Save paper and create handouts.
Using N-Up PDF doesn't require an account, an email address, or a paid plan. Your file is held in temp memory only for the duration of processing, then permanently unlinked. No watermarks, no upsells, no behavioural tracking.
Print-industry terminology: '2-up' = 2 pages per sheet, '4-up' = 4 per sheet, etc. Saves paper and ink for review prints.
Original page numbers (rendered on the page) shrink with the page. Add new page numbers afterwards if you need them readable.
2-up and 8-up work well for landscape, 4-up and 9-up for portrait. Mismatches add whitespace around each sub-page.
