SVG (Scalable Vector Graphics) is an open standard used to describe two-dimensional vector graphics. It is great for diagrams and shapes, while PNGs are better for photographs. SVG files are a bit like instructions on how to make an image. This means that they can be resized without looking pixelated or blocky.

An excellent tool with which to create SVG images for use in Tux Paint is Inkscape, a high-quality Open Source interactive drawing program available for Windows, macOS, and Linux. There are also other applications that can produce SVGs, both free/open source, and commerical/proprietary.
