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.

Performance

Extensive 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.


Layers

Usually 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.
