Like other software, such as Illustrator, Freehand, CorelDraw, or Xara X using the W3C standard Scalable Vector Graphics (SVG) file format, Inkscape also supports SVG features. In other words, Inkscape has markers, paths, clones, shapes, text, alpha blending, transforms, gradients, patterns, and grouping features which enable Inkscape to support SVG features.

Moreover, with the help of Inkscape, you can import formats such as JPEG, PNG, TIFF, and others. Even you can export PNG as well as multiple vector-based formats. Inkscape aims to generate a powerful and suitable drawing tool which complies fully with XML, SVG, and CSS standards.
