About the CBR Format
CBR stands for Comic Book RAR, and the name is the whole specification: it is a RAR archive full of page images, usually JPEG, renamed so a comic reader knows to open it as a book rather than an archive. There is no comic-specific structure inside and no compression of the artwork itself: the images arrive already compressed, so the archive adds almost nothing. RAR's efficiency, the reason the format was chosen in the early 2000s, buys you very little on a file that is mostly JPEG.
Page order is decided by filename sorting, and that is where most CBR files go wrong. A scan named page1.jpg through page10.jpg sorts as 1, 10, 2, 3 in almost every reader, putting page ten second. Zero-padded names, page001.jpg, sort correctly everywhere. If a comic opens with the pages shuffled, the archive is fine and the naming is not, which no conversion can repair for you.
The practical case against CBR is RAR itself: it is proprietary, and a reader has to ship a licensed or reverse-engineered decoder to open your file. Archivists and most reader apps have settled on CBZ for exactly that reason. Converting CBR to CBZ is a repack: the page images are copied across untouched, so nothing is re-encoded and nothing degrades. Converting to PDF gives you something any device can open and print, at the cost of a larger file and the loss of reader features like manga right-to-left paging.
