What is auto compress ? How does it work ?

During the process of uploading images to the media library, the plugin simultaneously sends the images to one of the API servers, where the incoming material is processed and sent back in optimised form. Afterwards, the plugin saves the image version with a reduced file size in the media library. The image can be reverted to the original if needed.

The optimization of images – including thumbnails – is conducted in the background and outside of the view of the user.
