Perfect Viewer supports JPEG, PNG, GIF, and BMP images; as well as CBZ, ZIP, CBR, RAR, 7Z, CB7, and LZH compressed files. As if this wasn’t enough, you can add a plugin that can be downloaded from the author's website to view PDF documents.
The application comes with five comic viewing modes that let you see the comic's original size, the screen-adjusted size, the size that has been exclusively height or width adjusted, and the customized size. It also supports left to right and right to left reading.
Another positive feature on Perfect Viewer is that it isn’t only a comic viewer, but also doubles as a library and file organizer. So, from the app's interface, you can easily manage all of your comics by creating favorites, markers, folders, etc.
Perfect Viewer is a very complete comic viewer that is full of features which are aimed at allowing the reader to enjoy what he is seeing and reading.
