mtPaint is a simple painting program developed by Mark Tyler from scratch so you can easily create pixel art and manipulate digital photos.
It uses the GTK+ toolkit (version 1 or 2) and runs on PC’s via the GNU/Linux or Windows operating systems. Because of its simplicity it can also run on older PC hardware (e.g. a 200MHz CPU and 32MB of RAM).
By default it is in the English language, but there are also translations available for other languages such as Spanish, Czech, French, Portuguese and Brazilian Portuguese.
mtPaint is free software, released according to the GNU General Public License.
