A vector graphics editor is used to compose and edit vector graphics images. There are many popular vector graphics paid editors like Adobe Illustrator, CorelDraw, Xara etc.

Popular vector file formats are EPS, PDF, WMF, SVG, or VML. There are few very good free vector editor software also. Below I have listed three very good free vector editors.
Inkscape supports many advanced SVG features (markers, clones, alpha blending, etc.) and great care is taken in designing a streamlined interface. It is very easy to edit nodes, perform complex path operations, trace bitmaps and much more. We also aim to maintain a thriving user and developer community by using open, community-oriented development.
The interface is tailored for high productivity: it does never get in your way. Creative Docs .NET tools are simple, yet powerful. All styles and attributes can be modified interactively with a minimum number of mouse clicks. A color gradient, for instance, can be modified directly by dragging its handles in the document window.
