Fit More Pages on Each Sheet
Putting several pages on one sheet — often called "N-up" — is one of the most practical things you can do before printing. Two slides side by side make a readable handout; four pages on a sheet turn a long document into compact study notes; and either layout roughly halves or quarters the paper and ink a print run uses. It's also a quick way to make a one-page overview of a multi-page document for review.
How N-up Works
Each source page is embedded as a scalable object and placed into a cell of a grid on a fresh sheet: 2 per sheet uses A4 landscape with two cells side by side, and 4 per sheet uses A4 portrait with a two-by-two grid. Pages are scaled to fit their cell while keeping their proportions, so nothing is stretched. Because the original pages are embedded as vectors rather than re-rendered, text and line-work stay perfectly crisp.
The whole arrangement is built in your browser and the result is an ordinary PDF you can print or share — with no upload at any point.
Getting the Best Print
Choose 2-up for slides and anything text-heavy you still need to read comfortably; choose 4-up to maximize paper savings for reference material. In your printer dialog, set scaling to "Actual size" or "100%" so the tool's layout isn't shrunk again, and print double-sided to halve the paper once more.
