Convert CBR to JPG

Comic Book Archive (.cbr) is really just renamed RAR file which contains pictures (one for each page) that form the comic. In case that you need the pictures, simply rename CBR to RAR and extract them and that's it, no cbr to jpg conversion is required. In some cases, pictures inside .cbr files are saved in PNG format instead JPEG, which means you have to convert them using a graphics converter should you need it.
