Is my file uploaded to a server?

No. This tool runs entirely in your browser via WebAssembly — your file never leaves your device. You can verify this in your browser's DevTools Network tab.

How many pages can I fit on one sheet?

Choose 2-up, 4-up, 6-up, or 9-up. Each source page is scaled to fit its cell while keeping its aspect ratio.

What happens if the page count doesn't fill the last sheet?

The remaining cells on the final sheet are simply left blank — no pages are dropped or duplicated.

N-up Layout

Place several pages on one sheet to save paper when printing — nothing is uploaded.
