+description: Optimize images with Layer0's optimization service
+navigation:
+  title: Layer0
+---
+
+Layer0 provides a simple HTTP service for optimizing images.
+
+:::alert{type="info"}
+The image optimizer will only return an optimized image for mobile browsers. Desktop browsers are served the original image.
+:::

+This integration works out of the box without need to configure!  See the [Documentation](https://docs.layer0.co/guides/image_optimization) for more information.
+
+**Example:**
+
+```vue
+<nuxt-img provider="layer0" src="https://i.imgur.com/LFtQeX2.jpeg" width="200" height="200" quality="80" />
+```
+
+## Modifiers
+
+Layer0 supports the following modifiers: `height`, `width` and `quality`
+
+## Options
+
+### `baseURL`
