Nowadays, whether it is a mobile phone or a camera, the resolution of the photos taken is getting higher and higher, and the picture files are getting bigger and bigger. They not only take up a lot of disk space for local storage, but also consume a lot of time and bandwidth during the process of transferring and uploading to the website. As a result, we generally need to use tools to compress image files.
Caesium Image Compressor is a free, open-source image compression program for Windows and Mac platforms, developed by SaeraSoft (Matteo Paonessa) from Italy. It can bring convenience to photographers, bloggers, webmasters, businesses or casual users when storing, sending and sharing digital images. It can compress the volume of pictures to 10% of their original size without noticeable loss of quality, thus saving a lot of storage space and network traffic.
Caesium Image Compressor has a simple user interface without too many setting items, supports drag-and-drop operation, supports batch operation and lossless compression, allows to keep metadata, supports real-time preview and comparison of before and after effects of image compression (so that users can adjust the compression parameters as required), and provides online and command line versions. In addition, it also has functions such as image format conversion, image resolution adjustment, and renaming of all images with custom suffix.
