A CBZ file operates as a standard ZIP repurposed for comics, containing sequentially named image pages so readers can sort them, sometimes including covers, subfolders, bonus art, or `ComicInfo.xml`, and comic software provides features like continuous scroll and manga mode; if you want the raw images you can treat it like any ZIP, and CBZ became common because it keeps large sets of pages organized and easy to store.
A CBZ file being “a ZIP file with a comic label” means the file’s insides follow the standard ZIP structure, 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 differ only in name rather than content, but .cbz enables automatic detection in comic apps, letting them present pages with features like page flipping and right-to-left reading, whereas .zip generally opens as a compressed folder; CBZ relies on ZIP for broad compatibility, with CBR (RAR-based), CB7 (7z-based), and CBT (TAR-based) providing similar image bundles but with different levels of app support.
In real-world terms, the “best” format is whichever format your reader handles gracefully, and CBZ tends to win because ZIP is universal, though other comic archives work when supported; comic apps interpret CBZ as a page-by-page book with manga mode, spreads, and bookmarks, instead of exposing raw files like an archive tool would.
A comic reader app “reads” a CBZ by scanning it for usable page files, ordering them based on filename sorting, and loading only the necessary images into memory as you turn pages, rendering them according to your preferred layout (fit-to-screen, continuous modes, manga direction), and saving your place while producing a cover thumbnail for display in its comic library.
Inside a CBZ file you typically find the comic assembled as a ZIP of numbered images, usually JPEG but sometimes PNG or WEBP, named with leading zeros for correct ordering; a cover image is often included, subfolders can show up, and metadata like `ComicInfo.
