OptiPNG FileType (2019-05-07)

Recommended Posts

This plugin integrates OptiPNG with Paint.NET. It optimizes PNG to make them smaller in file size.


Both OptiPngFileType.dll and optipng.exe need to be in the FileTypes directory.


This plugin is compatible with Paint.NET v3.5 and v4.x.







- Image Resolution is now retained.

- UI fixes for HiDPI and Dark Theme.

- The bundled OptiPNG executable is at the latest version (0.7.7)


Based on code from @I Like Pi and @null54.
