pdfAbout N-Up PDF Tool
N-Up PDF Tool is a single-page tool for the common PDF document workflow task it is named after. Arrange two PDF pages per sheet (2-up layout) on landscape A4 pages for efficient printing. The interface keeps the input on one side, the configurable options in the middle, and the result on the other side. Most jobs start and finish without any scrolling.
Typical users of N-Up PDF Tool include legal teams preparing exhibit bundles, small-business owners sending invoices and students assembling reading packets. The thread connecting all of them is the same: a focused PDF document workflow task that fits cleanly into a browser tab and benefits from a tool with sensible defaults and minimal setup.
The execution path is auditable from the page itself: open developer tools, switch to the Network tab, run a job. The requests you see are static-asset GETs for the engine and the page resources. The actual work is JavaScript code running against the bytes already in your tab's memory.
N-Up PDF Tool is implemented on top of the open-source pdf-lib JavaScript library. The accepted input formats are PDF, decoded in the browser, processed, and re-encoded into the output format. Files up to 200 MB are well within the comfort zone of any modern browser.
Most people land on N-Up PDF Tool via a search at the moment they actually need the tool. That shapes the design: the page is a single screen with the input on one side, the controls in the middle, and the result on the other, so a first-time visitor can complete the job without reading documentation.
If your task needs more than one step, chain N-Up PDF Tool with Extract Single PDF Page, Split Pages Horizontally, and Interleave PDF Pages. Each tool produces output that is a clean input to the next, so multi-step workflows are just a matter of opening the next tool in a new tab and continuing.
The download is delivered as `{name}-2up.pdf` the moment processing completes — no email link, no "your result will be ready in 5 minutes" queue, no expiry timer. The file is generated in your browser and saved by your browser's normal download flow.
The 200 MB ceiling on input size is the only fixed limit. Output files are produced in standard formats that every common viewer recognises, and the tool runs the same way regardless of how many times you have used it during the session.
Some notes on the design of N-Up PDF Tool. The page is intentionally narrow: one input, the controls relevant to the task, and one output. Adding unrelated features would make the common case slower for the majority of users, so the surface is held to what people actually use.
Some context on why N-Up PDF Tool exists in this form: modern File APIs, high-performance JavaScript engines, and well-maintained open-source libraries now make it possible to perform PDF document workflow work entirely in the browser. N-Up PDF Tool is built on top of that capability, which is why a single page can host the full pipeline.
Tips from users who reach for N-Up PDF Tool regularly: process one input first to confirm the settings produce what you expect before committing to a batch; treat the page as the working surface and avoid leaving large jobs running in a backgrounded tab where the browser may throttle JavaScript; and if a particular file fails, check whether the source is intact by opening it in its native viewer — most "tool errors" are actually input errors.
If N-Up PDF Tool appears to hang, the engine is almost certainly still working — large inputs simply take longer to process inside a browser than they would on a server with multi-core scheduling. For inputs near the 200 MB cap, give it up to a minute on a typical laptop before assuming something is stuck.
As a single-page tool, N-Up PDF Tool stays focused on one PDF document workflow step. Multi-step workflows are composed by chaining adjacent tools — each tool produces a standard file the next one can read directly, so a longer pipeline is just a sequence of short tab-and-tab visits.
N-Up PDF Tool is intentionally narrow in scope so the common case is fast and the result is predictable. If you ever need a variation it does not cover, browse the rest of the catalog — there is a good chance an adjacent tool already exists, and switching between tools is just a matter of opening another tab.
How it works
- 1Reach the N-Up PDF Tool page in your browser to begin.
- 2Select the PDF file you want to process — drag-and-drop and the file picker both work.
- 3Adjust the options to match what you need. Sensible defaults cover the most common case, so you can usually skip this step.
- 4Trigger processing. the open-source pdf-lib JavaScript library reads your input, applies the transformation, and writes the result back into the page.
- 5Download the result as `{name}-2up.pdf`. The file is generated in your browser and saved through your normal download flow.
- 6Repeat the process for additional inputs whenever you need to. The page stays loaded, so subsequent runs are quick.

FAQ
What is N-Up?
N-Up arranges multiple source pages onto a single output sheet, reducing paper usage when printing.
Layout?
2 source pages are placed side by side on each landscape A4 output page with 5mm gaps.
Scaling?
Each source page is scaled to fit its cell while maintaining its aspect ratio.
Private?
Yes — everything runs in your browser. No file ever leaves your device.
Are there any hidden fees with N-Up PDF Tool?
N-Up PDF Tool is free to use. The processing runs in your browser, which keeps the per-user cost low enough that the tool can be offered openly. The download is the same file the engine produced — you can use it for as many runs as you need.
Can I call N-Up PDF Tool from a script?
N-Up PDF Tool is a browser-only tool by design and does not expose a hosted API. The reason is the same as the privacy story: there is no Favtoo backend doing the work, so there is no service to call. If you need to script the same transformation, the underlying engine (the open-source pdf-lib JavaScript library) is open-source and can be used directly from your own code.
Can I self-host N-Up PDF Tool for my team?
N-Up PDF Tool is a static page running an open-source engine in your browser, so a typical corporate firewall does not get in the way as long as it allows JavaScript to load from Favtoo. For teams that need to host it themselves on an internal network, the underlying engine (the open-source pdf-lib JavaScript library) is open-source and can be packaged into a private build with the same behaviour. Reach out via the Contact page if that is something you are exploring.
What does N-Up PDF Tool do that command-line tools do not?
Desktop apps usually have more advanced features but require installation, maintenance and (often) a licence. Paid online tools are convenient but route your file through their servers and gate downloads behind accounts. N-Up PDF Tool sits in between: free, instant, and private, but intentionally narrow in scope. For one-off jobs and the common PDF document workflow operations, it is usually the lowest-friction choice; for highly specialised work, a dedicated app is still the right answer.
How do I know I am using the latest version of N-Up PDF Tool?
N-Up PDF Tool is updated whenever the underlying engine releases an improvement or a bug fix. Because the tool is delivered as a static page, every visit fetches the latest version automatically — there is no "version" to manage on your end. If a particular release ever changes default behaviour, the change is documented on Favtoo's changelog so you can confirm what shifted.
Is N-Up PDF Tool keyboard accessible?
N-Up PDF Tool uses native HTML controls wherever possible, which means keyboard navigation, focus rings, and screen-reader labels work the way the platform expects. The drop zone accepts files via the keyboard-accessible file picker as well as drag-and-drop, and result downloads use standard browser download flows. If you spot an accessibility gap, Favtoo treats it as a bug worth fixing.
What is the maximum file size for N-Up PDF Tool?
Inputs are capped at 200 MB per file, which keeps memory usage stable across phones, tablets and older laptops. You can run N-Up PDF Tool as often as you need; every run produces a full-quality result.
How fast is N-Up PDF Tool?
Most jobs finish in seconds. Speed scales with input size and with how many CPU cycles your browser tab has available — the engine runs in your browser, so it shares resources with whatever else you have open. For inputs near the 200 MB ceiling, expect anywhere from a few seconds to roughly a minute on a typical laptop. Closing other heavy tabs noticeably speeds things up.
What input formats are supported by N-Up PDF Tool?
N-Up PDF Tool accepts PDF. If your input is in a format that is not directly supported, convert it first using one of Favtoo's converter tools — every Favtoo converter outputs a file that is a clean input to the next tool in the chain.
