Frequently asked questions

Are my PDFs uploaded anywhere?

No. Merging happens entirely in your browser using pdf-lib, so your documents stay private.

How many PDFs can I merge?

As many as you like. Very large sets are only limited by your device's available memory.

Can I reorder the files before merging?

Yes — reorder them in the list before clicking Merge, and the final PDF follows that order.
