There's no lossless option it just reencodes the file at your chosen quality setting.Ĭaesium does provide support lossless PNG compression, although this has a major limitation. Click the Add program, choose your images, select an Output folder, click Compress and you'll have your results within seconds.īMP compression isn't of interest to us, and the program's JPG technology isn't anything special, either. Caesium is a simple open source tool that helps you to compress PNG, JPG and BMP formats.
