Inkscape is a vector graphics editor. It is used for both artistic and technical illustrations such as cartoons, clip art, logos, typography, diagrams, and flowcharts. It uses vector graphics to allow for sharp printouts and renderings at unlimited resolution and is not bound to a fixed number of pixels like raster graphics. It is free and open-source software released under a GNU General Public License (GPL) 2.0 or later.

Inkscape uses a file format defined by a technical standard named Scalable Vector Graphics (SVG) as its main format, which is supported by many other applications including web browsers. It can import and export various file formats, including Adobe Illustrator (AI), Encapsulated PostScript (EPS), PDF, PostScript (PS) and PNG.[5]
