Print shops and office printers behave best with one file: a single document means one print job, one set of settings, and no shuffled page order. Merging also lets you stamp continuous page numbers across what used to be separate files.
Drop the files, drag them into print order, switch on “Add page numbers” if you want a numbered packet, and merge. The result downloads instantly, with no upload and no account.
