Frequently asked questions
Can I change the order before merging?
Yes. Move files up or down before processing. The pages within each file keep their original order.
Does merging reduce PDF quality?
Pages are copied without rasterizing their text and graphics. This tool does not compress images or promise a smaller file.
Can I merge password-protected or signed PDFs?
No. Encrypted PDFs and interactive form or signature widgets are rejected. Use suitable unprotected copies and keep originals of signed documents.
