Your files never leave your device
Unlike most online PDF tools, PDFQuokka does the merging right here in your browser. Nothing is uploaded, stored, or seen by anyone — which makes it perfect for contracts, invoices and anything private.
Frequently asked questions
Are my files uploaded to a server?
No. PDFQuokka merges your PDFs entirely inside your browser using JavaScript. Your files never leave your device and nothing is sent to any server.
Is there a limit on the number or size of files?
There's no hard limit. Because the work happens on your own device, the practical limit is your computer's memory — very large files just take a little longer.
Can I choose the order of the PDFs?
Yes. After adding your files you can move each one up or down, and they're merged in exactly that order.
