Quality .jpg The compression for the .jpg image (0..100).
100 has best picture quality but image file size is the biggest.

Quality .png The compression for the .png image (0..9).
0 has best picture quality (no compression) but image file size is the biggest.
Usually, 3 to 5 give satisfying results
Quality .webp The compression for the .webp image (0..100).
100 has best picture quality but image file size is the biggest.
Usually, a quality of 60 gives good results (enough compression to make the file size small but not too much so that the image still looks good).

An image PHP extension is required for the creation of image thumbnails. The GD PHP extension is used by default. Make sure this extension is available on your service provider's server. The extension will detect this automatically.

New Joomla 4 The extension supports the Imagick PHP image extension. If Imagick is available on your server, you may use it instead of the GD extension. To do so, go to the SimplifyYourWeb extensions System plugin and select the preferred library.
