TweakPNG is a low-level utility for examining and modifying PNG image files. The current version requires Windows 2000 or higher (XP, Vista, etc.), though it is possible to build a copy that runs on Windows 95/98/ME. TweakPNG is licensed as Freeware which means the features included in the program are completely unlocked and the cost of the software is completely free which you can download without any cost.

TweakPNG is an excellent tool for web developers and others who wish to remove unwanted data and gamma information from Ping images. This provides for compatibility and perfect colours on all browsers.

To improve speed of optimization, you may want to add TweakPNG as a default "Open With" program on Windows XP - Windows 7.

The newest version contains:Support for 64-bit builds.Support for sCAL chunks.Allow drag/drop onto viewer window.Minor changes to shortcut keys, icons, etc.
