the application  optipng-ui  has been discontinued

OptiPNG-UI main window

The OptiPNG-UI application, that is the graphic interface I made in 2009 for the OptiPNG program created by Cosmin Truta (Canada), is no longer available.

A new project, named PNG ToolKit, completely replaces the previous application and contains many new functionalities; since this is not a simple update of the previous version, but a completely redesigned software, I've also decided to change the name to match it to the new contents.

I thank the over 20,000 users who downloaded OptiPNG-UI since 2009 to 2016, from more than 100 different countries.

If you want to continue to optimize your PNG images for free, you can use the Free version of PNG ToolKit.
