Caesium is an automatic photo compressing software that manages to reduce the file size on disk, without compromising the visual quality. The software is very intuitive and user-friendly and is also able to compress multiple images at once, up to 90%, without quality loss.
Users can set the compression level on each picture separately or set it for all the pictures at the same time. The interface is very user-friendly which makes the program even easier to use and understand; users can just drag and drop photos into the software window and they will automatically be added to a list. After setting the compression level, the Compress button will be clicked and the program will instantly do its job. After the process is complete, pictures can be reviewed and compared using the built-in preview option.
By default, the program will save the pictures in the same folder as the source files but it will also allow the user to add a suffix to the edited pictures. The supported file formats are: JPG, PNG, BMP, WMF, GIF.
