**SVG O**ptimizer is a Nodejs-based tool for optimizing SVG vector graphics files.
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.
SVGO has a plugin-based architecture, so almost every optimization is a separate plugin.
Today we have:

```sh $ svgo test.svg -o test.min.svg ```
```sh $ svgo test.svg other.svg third.svg ```
```sh $ svgo test.svg other.svg third.svg -o test.min.svg -o other.min.svg -o third.min.svg ```
with STDIN / STDOUT:
```sh $ cat test.svg | svgo -i - -o - > test.min.svg ```
with folder
```sh $ svgo -f ../path/to/folder/with/svg/files ```
or:
```sh $ svgo -f ../path/to/folder/with/svg/files -o ../path/to/folder/with/svg/output ```
```sh $ svgo *.svg -o ../path/to/folder/with/svg/output ```
with strings:
``‘sh $ svgo -s ’<svg version="1.1">test</svg>' -o test.min.svg ```
or even with Data URI base64:
``‘sh $ svgo -s 'data:image/svg+xml;base64,...’ -o test.min.svg ```
with SVGZ:
from .svgz
to .svg
:
```sh $ gunzip -c test.svgz | svgo -i - -o test.min.svg ```
from .svg
to .svgz
:
```sh $ svgo test.svg -o - | gzip -cfq9 > test.svgz ```
