Paint.NET was created as an alternative to the basic Microsoft Paint (integrated with Windows) but it became a much more complex and versatile graphics application. With a user-friendly interface, unsophisticated and free, Paint.NET nevertheless has some very advanced features that bring it more into the Photoshop and GIMP league.
Like any good graphics program, Paint.NET is constantly improving with new features and tools. A convenient way to do that is to develop new plugins and let the users make up their own mind whether they want to install them or not.
How to Install a Plugin in Paint.NET
Plugins usually come in a zip file that contains a .dll and a text file. The .dll is the actual plugin and the text file tells you how to install and implement it. Plugins need to be saved in a specific folder (usually Program Files/Paint.net/Effects if not specified otherwise in the readme file). Plugins enable you to add new effects, file types, fonts, etc.
