+# SVGO [![npm](https://img.shields.io/npm/v/svgo)](https://npmjs.org/package/svgo) [![chat](https://img.shields.io/discord/815166721315831868)](https://discord.gg/z8jX8NYxrE) [![docs](https://img.shields.io/badge/docs-svgo.dev-blue)](https://svgo.dev/)
+
+SVGO, short for **SVG O**ptimizer, is a Node.js library and command-line application for optimizing SVG files.
+
+## Why?
+
+SVG files, especially those exported from vector editors, usually contain a lot of redundant information. This includes editor metadata, comments, hidden elements, default or suboptimal values, and other stuff that can be safely removed or converted without impacting rendering.
+
+## Installation
+
+You can install SVGO globally through npm, yarn, or pnpm. Alternatively, drop the global flag (`global`/`-g`) to use it in your Node.js project.
+
+```sh
+# npm
+npm install -g svgo
+
+# yarn
+yarn global add svgo
+
+# pnpm
+pnpm add -g svgo
+```
+
+## Command-line usage
+
+Process single files:
+
+```sh
+svgo one.svg two.svg -o one.min.svg two.min.svg
+```
+
+Process a directory of files recursively with `-r`/`--recursive` and `-f`/`--folder`:
+
+```sh
+svgo -rf path/to/directory_with_svgs -o path/to/output_directory
+```
+
+Help for advanced usage:
+
+```sh
+svgo --help
+```
+
+## Configuration
+
+SVGO has a plugin architecture. You can read more about all plugins in [Plugins | SVGO Documentation](https://svgo.dev/docs/plugins/), and the default plugins in [Preset Default | SVGO Documentation](https://svgo.dev/docs/preset-default/).
+
+SVGO reads the configuration from `svgo.config.mjs` or the `--config path/to/config.mjs` command-line option. Some other parameters can be configured though command-line options too.
+
+**`svgo.config.mjs`**
+
+```js
+export default {
+  multipass: false, // boolean
+  datauri: 'base64', // 'base64'|'enc'|'unenc'
+  js2svg: {
+    indent: 4, // number
+    pretty: false, // boolean
+  },
+  plugins: [
+    'preset-default', // built-in plugins enabled by default
+    'prefixIds', // enable built-in plugins by name
+
+    // enable built-in plugins with an object to configure plugins
+    {
+      name: 'prefixIds',
+      params: {
+        prefix: 'uwu',
+      },
+    },
+  ],
+};
+```
+
+### Default preset
+
+Instead of configuring SVGO from scratch, you can tweak the default preset to suit your needs by configuring or disabling the respective plugin.
+
+**`svgo.config.mjs`**
+
+```js
+export default {
+  plugins: [
+    {
+      name: 'preset-default',
+      params: {
+        overrides: {
+          // disable a default plugin
+          cleanupIds: false,
+
+          // customize the params of a default plugin
+          inlineStyles: {
+            onlyMatchedOnce: false,
+          },
+        },
+      },
+    },
+  ],
+};
+```
+
+You can find a list of the default plugins in the order they run in [Preset Default | SVGO Documentation](https://svgo.dev/docs/preset-default/#plugins-list).
+
+### Custom plugins
+
+You can also specify custom plugins:
+
+**`svgo.config.mjs`**
+
+```js
+import importedPlugin from './imported-plugin';
+
+export default {
+  plugins: [
+    // plugin imported from another JavaScript file
+    importedPlugin,
+
+    // plugin defined inline
+    {
+      name: 'customPlugin',
+      params: {
+        paramName: 'paramValue',
+      },
+      fn: (ast, params, info) => {},
+    },
+  ],
+};
+```
+
+## API usage
+
+SVGO provides a few low level utilities.
+
+### optimize
+
+The core of SVGO is `optimize` function.
+
+```js
+import { optimize } from 'svgo';
+
+const result = optimize(svgString, {
+  path: 'path-to.svg', // recommended
+  multipass: true, // all other config fields are available here
+});
+
+const optimizedSvgString = result.data;
+```
+
+### loadConfig
+
+If you write a tool on top of SVGO you may want to resolve the `svgo.config.mjs` file.
+
+```js
+import { loadConfig } from 'svgo';
+
+const config = await loadConfig();
+```
+
+You can also specify a path and customize the current working directory.
+
+```js
+const config = await loadConfig(configFile, cwd);
+```
