cbzManager will convert any cbz,cbr,zip,rar,pdf comic books into a cbz archive using webp image encoding thus reducing the size of archives up to 50%. Even though this program has been thoroughly tested on a library of over 5500 comics we you should backup your data before you use this program. We strongly advise you perform a test run on a folder containing a few comics prior to converting your entire collection.
Choose a folder containing your comics and conversion will start automatically.

Pdf conversion is not enabled by default, you must activate it in the options menu. By default cbzManager uses 2 conversion threads but if you want more performances, set Options/Conversion queues to ‘Big’, beware this will use a lot of processing power. If you set the chosen folder as default folder (menu file/set as default), this folder will be monitored and whenever files are added to this folder, cbzManager will pick them up and automatically start conversion.

cbzManager contains powerfull editing features : delete, flip, rotate, crop/crop all, border removal, import/export, joining back split double pages, many image enhancing filters and more for managing comics.
You can specify an alternate temporary folder, if you have RAM available, create a RAM drive and point cbzManager to it (option menu), it will increase perfomances.

Everytime a file is modified or converted the original file is moved to the recycle bin, so if you convert a big library, watch your available disk space.
cbzManager will strip all extranous files (.nfo, thumbs.db, etc…) from the archive and clean the archive filenames (dots, dashes, and other annoying text will be removed), however xml metadata is preserved but it might become irrelevant as the contents ofvthecarchive will change. We are working on managing comics metadata.
