Does merging PDFs reduce quality?
No — merging PDFs does not reduce quality. The pages from each PDF are combined exactly as they are. Text, images, and formatting are all preserved at full quality.
Can I merge password-protected PDFs?
No — you need to remove the password from each PDF first (using Fourmeld's PDF unlock tool), then merge them. Re-apply password protection after merging if needed.
