Image Optimization

Larupload provides a feature to optimize images, which uses the 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.
