As an ASCII art editor, Monodraw's primary purpose is to generate plain text. But textual art requires a monospaced font environment which may not always be available.
So that you can easily embed your diagrams anywhere, starting from v0.8.4, the app can export in two image formats: PNG (raster) and SVG (vector). Both formats are widely supported across all operating systems and work on the web, too. SVG, as a vector format, allows you to use a single file which will look great on both Retina (high-DPI) and normal screens.
