Available as a limited time offer at $0.99 in the Mac App Store, PDF Hero is a Mac app to combine images and PDF files into a single document you can consequently export as PDF from within the app.
The concept is simple: PDF Hero acts as a “bucket” where you can drop multiple images and PDF files at once. With these files, the app will create a single document where each page contains the files you attached. It should come in handy for those who daily manage dozens of PDFs and find themselves constantly forwarding them to their colleagues or clients, or users who do a lot of image -> PDF converting. In this way, with just a drag & drop, you can create a single document containing everything you need. Please note that the current version of PDF Hero only supports PDFs and images – sadly, .txt or .rtf files won’t be attached. But there is a nice trick I noticed (fluid animations when flicking through attached files aside), and it’s the possibility to keep attaching files to an existing set without having to start over (see screenshot above).
That said, PDF Hero won’t get you to the top of PDF editing and management, but it’s a cool utility to merge images and other documents in seconds. Give it a try.
