Features

Simple, intuitive, and innovative user interfaceEvery feature and user interface element was designed to be immediately intuitive and quickly learnable without assistance. In order to handle multiple images easily, Paint.NET uses a tabbed document interface. The tabs display a live thumbnail of the image instead of a text description. This makes navigation very simple and fast. The interface is also enhanced for Aero Glass if you are using Windows 7 or Vista.

PerformanceExtensive work has gone into making Paint.NET the fastest image editor available. Whether you have a netbook with a power-conscious Atom CPU, or a Dual Intel Xeon workstation with 8 blazingly fast processing cores, you can expect Paint.NET to start up quickly and be responsive to every mouse click.

LayersUsually only found on expensive or complicated professional software, layers form the basis for a rich image composition experience. You may think of them as a stack of transparency slides that, when viewed together at the same time, form one image. System Requirements Minimum System Windows 8 or 8.1,    or Windows 7 (SP1 recommended),    or Windows XP SP3,    or Windows Vista SP1 (SP2 and Platform Update recommended) 800MHz processor (dual-core recommended) 512MB of RAM 1024 x 768 screen resolution 200+ MB hard drive space Optional: 64-bit mode requires a 64-bit CPU and a 64-bit edition of Windows Paint.NET does not work on Windows RT. Paint.NET depends on Microsoft's .NET Framework 3.5 SP1, which is automatically installed if it isn't already on the system. Paint.NET uses your hard drive to store temporary files related to undo/redo history. Because of this, actual disk space requirements will depend on the actions you perform on an image, and on the size of the image. http://www.getpaint.net/download.html
