Xee³ is a lightweight, fast and convenient image viewer and browser. It is designed to be a serious tool for image viewing and management, with a sleek and powerful interface.
Xee³ is useful as a more powerful replacement for Preview, or most any other image viewer available on OS X. It is very fast, and uses less memory than most other image viewing tools. It also uses OpenGL to display and scroll images much more smoothly than other viewers. Its interface is highly streamlined and has easily configurable keyboard shortcuts.
