Calibre already had an output profile for ZIP, but not CBZ, and there didn't seem to be any utility to quickly switch the extension before sending to a device. Whenever I zoomed on an image, the text was unclear and on my Kobo Clara HD I couldn't even zoom on it because it seems to only allow zooming on CBZ / CBR files. I made this plugin because I was annoyed at the very low resolution of comics / manga that were converted (from kindle / AZW) to EPUB through calibre. Simple plugin that will convert all ZIP / RAR format books in the active library to CBZ /CBR automatically each time a book is added / imported / converted.
