Caesium Review

Felix Cheng
Compresses images for fast loading and better storage
A review of Caesium by Felix Cheng

Caesium is a quick and easy image compression application which can perform compressions as batch operations.

This application is compatible with the most compatible image formats, most importantly PNG, GIF, JPG, GMP and WMF.

Caesium is extremely easy to use. The steps to compressing your images are involve adding the images you want to compress with the toolbar buttons or by dragging them from Windows Explorer. From the options section, set the quality you would like your final images to be converted to and the directory you want the final images saved in.

Before you start compressing files, Caesium shows you a preview of what the final images will look like. Compression ratio is displayed.

This program is quick, easy and totally free allowing users to achieve upto 90% compression rates without affecting the quality of the image. Overall, a good image compressor.
