Combine several PDF files into a single PDF.
AddPDF is a utility for combining several PDF files into a single, multipage PDF file; or splitting multipage PDF files into multiple single page PDFs, one per page.
Simply drag PDF files, or other file types which can be automatically converted, into the file list, re-arrange them using drag-and-drop, and then click the "Add" or "Split" button to combine or split them. Add transparent watermarks to each page with the "Stamp" button and "Alpha" control.
