Can I merge password-protected PDFs?

Encrypted and password-protected PDFs are not supported. Remove protection using an authorized PDF application first.

Will forms, bookmarks, and signatures be preserved?

This tool combines pages. Interactive forms, bookmarks, and digital signatures may not be preserved. Keep your originals and check the downloaded document.
