A CBZ file uses ZIP compression under a comic extension, where properly ordered filenames ensure page sequence, with occasional covers, metadata, and subfolders included; comic apps interpret the images as pages, but any archive tool can extract them, making CBZ a convenient way to distribute and manage large numbers of comic images.
A CBZ file being “a ZIP file with a comic label” signifies the only special part is the .cbz extension, and the extension simply prompts apps to display its numbered images as comic pages rather than a standard folder of files; since it’s still ZIP, you can rename it to .zip or open it with archive utilities to extract all pages, with the extension alone determining whether a comic reader or an archive tool handles it by default.
A CBZ and a ZIP use the same ZIP compression, but the .cbz extension ensures comic software recognizes and imports the file as a comic, while .zip defaults to archive tools; this makes .cbz a convenience label rather than a new format, and other comic archives follow the same pattern: CBR for RAR, CB7 for 7z, and CBT for TAR, each varying in compatibility depending on the reader.
In real-world terms, the “best” format is simply whatever your devices read most reliably, which makes CBZ the safest default, while CBR/CB7/CBT work fine if your reader supports them—and converting to CBZ is easy because you’re just re-packaging the same page images; opening a CBZ “like a comic” means an app reads the images in order and presents them as pages with zooming, scrolling, spreads, and bookmarking, instead of treating the archive as a folder of files.
A comic reader app “reads” a CBZ by scanning the ZIP structure for page-like files, filtering out non-page items, sorting filenames into the correct order, and then selectively decompressing the current and upcoming pages to memory for fast navigation, applying your view settings (scrolling, zoom, spreads), remembering your last page, and creating a cover preview for the library interface.

Inside a CBZ file you typically find a structured archive of image pages, usually JPEGs with the occasional PNG/WEBP, named in numeric order so sorting behaves properly; a cover file may be explicitly named or simply the first page, and although folders and metadata like `ComicInfo.xml` may appear, plus the odd junk file, the main purpose is a clean sequence of images for comic readers.
