Frequently asked questions

Are my PDFs uploaded to a server?

No. The files are read and combined entirely in your browser with the pdf-lib library. They never leave your device — ideal for contracts, statements and other private documents.

Is there a limit on the number or size of files?

No hard limits. Everything runs on your own device, so there are no server quotas. Very large files just take a little longer, depending on your hardware.

Can I reorder the pages before merging?

Yes. Each file appears in a list with up and down arrows — arrange them in any order, then merge. The final PDF follows that order exactly.

Your privacy is built in

Everything runs locally in your browser. Your files and data are never uploaded to any server.
