PDFactory - your PDF toolbox.
Using Drag & Drop you are able to re-order the pages, to insert and remove them and to drag pages from one document to another. Additionally you can split and (re-)merge PDF documents easily.
The innovative Drop Box lets you convert your pictures into PDF documents - simply by dragging them from the Finder into PDFactory.
And most exciting is the ability to copy with one click the entire text content of the document or of pages into the clipboard to use them in other applications.
