A CBZ file is a comic book archive format. It is essentially a ZIP archive containing a series of image files, typically in JPEG, PNG, or GIF format, representing the pages of a comic book. The images are usually ordered numerically or alphabetically to ensure proper reading sequence. CBZ files are commonly used for distributing and reading digital comics, manga, and other sequential art. The format is widely supported by comic book reader applications across various platforms, making it a convenient way to store and access digital comic collections. The simplicity of the format, relying on standard ZIP compression and common image formats, contributes to its widespread adoption. Users can easily create CBZ files by zipping a folder of images and renaming the extension to .cbz. This allows for easy sharing and archiving of comic book content.
