Combine Pages (N-up) PDF

What "N-up" means

N-up printing shrinks several of your original pages and arranges them side by side on a single larger sheet. A 2-up layout puts two pages on one landscape sheet; a 4-up layout tiles four pages in a 2 × 2 grid on a portrait sheet. It is the fastest way to turn a long document into a compact handout, a set of thumbnails, or a paper-saving proof you can scan at a glance.

Why combine pages this way

Fewer sheets means less paper, less ink, and a lighter file to carry. Teachers use N-up for reading packets, developers print code reviews two-up, and crafters lay out proofs before committing to a full-size run. Because each original page is scaled and centered inside its cell — never stretched — your artwork and text keep their proportions and stay readable.

FAQ

Is my PDF uploaded anywhere?

No. The whole process runs inside your browser using pdf-lib. Your file is never sent to a server.

What if my page count is not a multiple of 2 or 4?

That is fine. The last sheet simply holds fewer pages, leaving the remaining cells blank.

Will mixed page sizes work?

Yes. Each page is scaled to fit its cell independently, so documents with different page dimensions still line up neatly.

Why is 2-up landscape and 4-up portrait?

Those orientations give each original page the most room, keeping text crisp and avoiding wasted margins.
