Merge PDF — FAQ
Is merging PDFs free?
Yes — combine unlimited PDFs for free, with no signup and no watermark. Pro (NZ$9/mo) adds batch jobs, no size caps and saved history, but merging itself is always free.
Do my documents get uploaded?
No. The merge happens locally in your browser with pdf-lib. Your files never leave your device and nothing is stored on a server.
Can I reorder the PDFs before merging?
Yes. Each file has up and down controls so you can arrange them in exactly the order you want before combining.
Is there a limit on how many PDFs I can merge?
There is no hard limit in the free tool. Very large jobs depend on your device’s memory, since everything runs locally.
Will the original formatting be preserved?
Yes. Pages are copied as-is into the new document, so text, images and layout stay intact.
