PDF Architect is an application that opens PDF documents. We advertise that PDF Architect can work with 300+ file types because any file that can be printed can also be converted to PDF with the virtual printer that’s installed along with PDF Architect.

A file must be converted into a PDF document before it can be opened with PDF Architect. If you drag and drop a file on the PDF Architect icon on your desktop, the file will be converted as it opens. This is especially useful with CBR or CBZ files.

PDF Architect also opens the WWF file format.

If you don't have PDF Architect yet, you can purchase it here.
