.cbz is a file extension which stands for Comic Book Zip Archive. Multiple images, usually .JPEG and .PNG, are organized and saved into comic-like pages. CBZ file format is used to view and compress multiple files into a single file for convenience. The CBZ file extension does this by allowing the user to manipulate large files to their liking.
The .fb2 filename extension refers to the open XML based eBook format known as FictionBook. The file format was developed by Dmitry Gribov with an initial release in 2004, quickly gaining popularity in Russia. The format is open which in this context means it has no compatibility with digital rights management technologies. The structure of the format splits the contents of the data into three sections; title information, XML document information, and finally information about the paper edition which is optional.

.CBZ file is a .ZIP file which has been renamed in order to differentiate it from a general image viewer to a specialized one for comic books. The .cbz file extension was developed at about the same time as the .cbr file format because they were both made popular by CDisplay image viewer developed by David Ayton and released in April 2004. CDR and CBZ formats were first supported by CDisplay application.
Being extended from the XML format, the FictionBook file format describes the structure of the documents content, supporting metadata such as author, title, as well as special tags for quotations and epigraphs. Unicode is the supported character set used with the format. To display supported raster images, the images are first converted to a base 64 stream and contained within a binary tag. Plain text data typically loads first, being located at the top of the file with images allowed to load later in sequence.
