PDF Champ PDF Password Remover worked really well when I had to access a few locked office files. I used it mainly for reports that were not allowing print and copy options. The good part was that after removing the restrictions, the formatting stayed exactly the same. Fonts, images, and tables looked just like the original file. It also worked smoothly with strongly secured PDFs, including AES encrypted files. The process was simple and did not take much time. I also liked that the software worked offline, which felt safer for important documents. The demo version was helpful before going for the full version.
