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.
