Caesium is an image compression software that helps you store, send and share digital pictures, supporting JPG, PNG, WebP and TIFF formats. You can quickly reduce the file size (and resolution, if you want) by preserving the overall quality of the image.
This advanced import method cannot be like the 2.6 version where you can drag and drop images directly into the software. You must click on the option to add files or folders. You cannot drag and drop folders into the software, which is very inconvenient. It is more convenient to drag and drop into the software like in the 2.6 version.
