Frequently asked questions

Are my PDFs uploaded?

No. The PDFs are combined in your browser with the open-source pdf-lib library, so private documents stay on your device.

Will the merged PDF lose quality?

No. Pages are copied as they are, so text stays selectable and images keep their resolution.

Can I merge password-protected PDFs?

Encrypted PDFs usually can't be merged. Remove the password in your PDF reader first, then try again.
