**SVG O**ptimizer is a Node.js-based tool for optimizing SVG vector graphics files.
## Why?
SVG files, especially those exported from various editors, usually contain a lot of redundant and useless information. This can include editor metadata, comments, hidden elements, default or non-optimal values and other stuff that can be safely removed or converted without affecting the SVG rendering result.
## Installation
```sh
npm -g install svgo
```
or
```sh
yarn global add svgo
```
## CLI usage
```sh
svgo one.svg two.svg -o one.min.svg two.min.svg
```
Or use the `--folder`/`-f` flag to optimize a whole folder of SVG icons
