Frequently asked questions

How do I merge PDF files into one?

Select or drop the PDFs you want to combine, arrange them in the order you want, then click merge and download the single combined PDF.

Is there a limit on how many PDFs I can merge?

There is no fixed limit. Because processing happens in your browser, the practical limit depends on your device's available memory.

Are my files uploaded to a server?

No. Merging runs entirely on your device, so your documents stay private and never leave your browser.
