It aims to replace MacPaint, an image editor for the classic Mac OS last released in 1988.

It has basic raster image editing capabilities and a simple interface designed for ease of use.

The application also is often used for pixel art because of its grid option, and is not made for large scale images or GIMP or Photoshop-like editing on pictures or photographs.

There are adjustable stroke sizes which pertain to the brush, eraser, and spray can tools.

Like Microsoft Paint, it can export all of the universal image formats such as PNG, JPEG, BMP, GIF, or TIFF.
