# Image Optimization

Larupload provides a feature to optimize images, which uses the [`spatie/image-optimizer`](https://github.com/spatie/image-optimizer) package. This feature is disabled by default, but can be enabled by configuring the `optimize` option in the Larupload configuration file. Once enabled, the package will automatically optimize the images upon upload, reducing their file size without compromising their quality. You can also set a custom optimizer for each image type (jpg, png, svg, gif, webp) by providing a configuration for each. This feature can significantly improve the performance of your application by reducing the size of images being served.
