Here are several drawing and painting programs for the little ones (and not so little). Some are simpler, but we'll also talk about more complex platforms that adults can enjoy too. All of them include pencil, eraser, and a color palette, and let you add and reproduce frames and export the drawing in different formats.
Krita
We start with Krita, one of the most advanced drawing tools on the market, thanks to its large number of services and features. You can draw freehand, use the magic wand, different brushes, add filters and layers, and export your work in PDF format. You can also use the platform to edit or retouch images. The program is ideal for kids who have more experience with drawing and painting platforms. Krita is a free program available for Windows, Mac OS X, and Linux. (Verified with Virustotal).
Autodesk SketchBook
Next up is a powerhouse drawing program: Autodesk SketchBook. It comes with pencil, marker, airbrush, eraser, pen, felt-tip pen, bristle brush, lasso, layers, and more. When you're done, you can export your drawing in different formats (TIFF, BMP, PSD, PXD, etc.). Autodesk SketchBook is a free program available for Windows, Mac OS X, iOS, and Android.

Tux Paint
Tux Paint is a drawing program with seven very useful tools (Paint, Magic, Stamp, Text, Label, Shapes, and Lines). Each service comes with several features that make your drawing more professional. It's really great for kids or beginners, thanks to its very simple interface. Tux Paint is a free program available for Windows, Mac OS X, and Linux. (Verified with Virustotal).
Baby Paint
Baby Paint is also a drawing platform with only the basic drawing tools, and with it you can create a work from scratch or edit and retouch images. Baby Paint is a simple tool for kids or people with little computer knowledge to make their drawings or paintings with the basic options. Baby Paint is a free program available for Windows. It uses the Softpedia download platform. (Verified with Virustotal).
LittlePainter
We'll finish with LittlePainter, a very good platform for kids and some adults to let their creativity run wild. With its tools you can make great drawings or paintings. Among its functions are circle, brush, text, paint bucket, line, curve, brush, and color palettes, so you can make custom drawings or edit images. LittlePainter is a free, portable program available for Windows. (Verified with Virustotal).
The drawing and painting programs for children presented here can be used by kids with little knowledge of these platforms, or by children, teenagers, and adults with more advanced knowledge.
