CbxConverter is a freeware to bulk compress cbr, cbz, and ePub files. It greatly reduces the size of your comic files and helps to save disk space. It can compress input files up to 50% or more which is really great. It automatically optimizes images available in your comic files and compresses those images to reduce the size.

Although, it reduces the quality of images to compress your cbr/cbz/ePub files. Still, it produces good quality output files, and you won’t be able to distinguish between compressed and original files.

You can also set the resize (compression) percentage manually. Benefit of this feature is that you will be able to set different compression level for different files. It’s a powerful software to reduce multiple comic files together.

CbxConverter is really a handy software to convert multiple comic files. I liked its feature to set separate compression level for every single file and feature to convert ePub files into cbz files.
