What is a CBR file?
CBR stands for Comic Book RAR and is a popular format for digital comic books. It is a compressed archive that contains a sequence of images (usually in JPEG or PNG format) and uses the RAR compression algorithm.
CBR files allow users to view comic pages in order with compatible readers. Though it's essentially a RAR file, it is recognized by comic reading apps for easy navigation and display.
How to open CBR files
CBR files can be opened using comic book readers like CDisplayEx, MComix, YACReader, and Sumatra PDF. They can also be unpacked with WinRAR or 7-Zip to access individual images.
