"PDF Architect is a modular program that offers three separate packages (Standard, Professional, PRO + OCR). Each package contains a set of modules for the software, which determine the editing capabilities of the PDF. Can be purchased selectively according to their specific needs. It's unlike other overall PDF editor features that are all bundled together."
"Some documents are edited with PDF Architect, and if opened with another PDF Reader, for example, in Adobe Reader, sometimes there will be freeze and lockup."
