Caesium is a simple tool with which we will be able to reduce the size of the images without losing quality. At first glance it will seem as if they have the same quality, but one of them will occupy a lot less space.
This is accomplished by means of a simple process: first we choose the images that we want to compress, the output format, that can be either JPG, PNG or BMP, the output quality and last of all, the destination folder. And thanks to the preview window we will be able to check the result before compressing the photographs.
With these simple steps, Caesium will create compressed copies of the images, reducing their size.
