PaintBox

Similar to the Paint program found in Windows, PaintBox provides an environment in which you can draw. But it comes with additional features.
Because installation is not necessary, PaintBox is a portable app. It means that you can place it on an external device and directly run its executable file on any computer. More importantly, the Windows registry items will not be modified.
The interface of the software is familiar and easy to navigate through. You can create a new picture after setting its width, height and canvas color.
So, you can use basic tools, such as pen, special pen, fill, spray can, shapes, text, color picker, drag, zoom, magic wand, rectangle and freehand select.
In addition, you can flip, mirror, resize, rotate, crop or resample the image, enlarge the canvas, as well as apply effects (blur, brightness, contrast, gamma, RGB, grayscale, negative).
Furthermore, you can display a viewer, clipboard viewer and zoom grid, disable toolbars, print the image, clear the current selection, use the undo, redo, cut, copy and paste functions, and more.
PaintBox runs on very low system resources and didn't pop up any errors, freeze or crash during our tests. On the other hand, there is no help file available and the program doesn't come with enough advanced settings. For example, there is a limited range of effects.
All in all, PaintBox is certainly not an impressive application but it is simple to use and stable. We mainly recommend it to first-time users.
