Now you can draw new SVGs online on clker.com, thanks to svg-edit. This tool can edit the existing SVGs or be used to create a new SVG image from scratch. I disabled editing using IE due to buggy behavior, but the edit functionality works almost fine in chrome, safari, firefox and opera.
Now, you can upload a raster image to be vectorized then edit it and remove unwanted regions all online on clker.com ! .
Happy designing and editing
