Are Svg Files Editable. Use an SVG editor - that would be Illustrator or Inkscape. Once your done editing remember to save your design in svg file format.
Simply drag and drop your SVG file or icon into the editor canvas.
The svg files need to be opened in a vector graphics software application such as Adobe Illustrator CorelDraw or Inkscape a free and open-source vector graphics editor which runs on Windows Mac OS X and Linux. Whether its the editing of shapes or adjustment of gradient fills most of the action is taking place directly on the canvas. If you alter opacity at the layer level the resulting SVG file will not display transparency as it appears in Illustrator. You shouldnt have to clean it up.
