How is this different from other online PDF tools?

Most online PDF tools send your files to a remote server for processing. This tool processes everything locally in your browser using client-side JavaScript. Your files are never transmitted to any server, which means your document content stays entirely under your control.

Are my PDF files uploaded?

No. Your files are read directly by your browser. Your files are never transmitted over the network. The tool works entirely within the browser tab you have open.

Can I verify that files are not uploaded?

Yes. Open your browser's developer tools (F12), go to the Network tab, and watch for any outgoing requests while using the tool. You will see no file data leave your browser. The site may record an anonymous page-view count, which never includes your files and can be disabled.

Does this tool work offline?

Yes, once the page has loaded the tool processes your files entirely in your browser; tool functionality needs no network connection. You can disconnect from the internet and continue using it.

What happens when I refresh the page?

Because nothing is stored on a server, refreshing the page clears your current session. Any files you had selected will need to be selected again.

Does this tool store my files?

No. Files are held in browser memory only for as long as the page is open. Closing or refreshing the page discards them. Nothing is written to disk by the tool, and nothing is sent to a server.

Can this tool unlock password-protected PDFs?

No. This tool does not attempt to remove or bypass PDF password protection. If you know the password, the Unlock PDF tool on this site can remove it locally; then this tool can process the file.

What technologies does this tool use?

This tool uses client-side JavaScript and pdf-lib to embed each source page and tile several of them onto each A4 sheet, entirely within your browser — your files never leave your browser.

Does this tool use WebAssembly?

No. This tool uses client-side JavaScript and pdf-lib for local PDF structure editing. No WebAssembly is involved.

How do I put multiple pages on one sheet with this tool?

Pick a PDF from your device, choose 2, 4, or 6 pages per sheet, then select Create to build the imposed file. When it is ready, save the result to your device — everything runs locally in your browser.

How many pages can I place on a single sheet?

You can choose 2, 4, or 6 source pages per sheet, which are arranged as a 1x2, 2x2, or 2x3 grid respectively. These three fixed layouts are the available options, and pages fill each sheet left to right, then top to bottom.

Why does my output have wide margins around each page, and what size are the sheets?

Every output sheet is A4 portrait, and each source page is scaled to fit its grid cell while keeping its original aspect ratio and staying centred. Source pages whose proportions differ from the cell (for example very wide or landscape pages) leave extra empty space, which shows up as wider margins.

Does the N-up (Pages per Sheet) tool cost anything to use?

The N-up (Pages per Sheet) tool is completely free — no account, no sign-up, and no cap on how many PDFs you can tile into multi-page-per-sheet layouts, and it always will be. Every step of the process — reading your PDF, scaling and arranging pages onto each A4 sheet, and generating the download — happens inside your own browser using pdf-lib, so your files are never sent to a server or touched by anyone but you.

Good to know: Output sheets are A4; the source pages are scaled to fit, so very wide or very tall pages will have wider margins.

How it works

Select a PDF file from your device using the file picker.
The file is read into browser memory — no data leaves your browser.
Choose how many pages to place on each A4 sheet: 2, 4, or 6.
pdf-lib scales each source page to fit its grid cell, preserving aspect ratio, and tiles them onto A4 sheets in your browser.

When to use this tool

A lecturer prints 4 slides per A4 sheet for handouts, cutting paper use by 75% with no extra software.
An office manager shrinks a 200-page manual to 50 double-sided sheets for a team workshop.
