A CBZ file acts as a normal ZIP file with a comic-friendly extension, holding page images—usually JPG/JPEG, sometimes PNG or WEBP—named in numbered order like `001.jpg`, `002.jpg` to keep pages sorted, often including a cover image and optional metadata such as `ComicInfo.xml`; comic apps open it like a book with features such as zoom and page flipping, while you can extract the raw images by opening it with 7-Zip or renaming it to `.zip`, and CBZ is popular because it keeps pages bundled cleanly and avoids mis-sorted loose files.

A CBZ file being “a ZIP file with a comic label” shows that CBZ is just ZIP in disguise, prompting comic apps to handle the file as a sequence of pages instead of a simple compressed folder; because the structure is still ZIP, renaming it to .zip or opening it directly with archive software works the same as any other ZIP, with extension-based app handling being the key factor.
A CBZ and a ZIP operate identically at the file-structure level, 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 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 processing it as a bundle of page images, determining order through filenames, decompressing pages just in time for display, rendering them with various reading modes and optional visual tweaks, and storing metadata like last-read position and a cover thumbnail so the CBZ behaves like a polished digital comic instead of a simple image archive.
Inside a CBZ file you typically find a sequence of image pages stored in a ZIP container, usually JPGs (common for scans) or occasionally PNG/WEBP, all numbered like `001.jpg`, `002.jpg` to enforce reading order; a cover might be the first page or a file named `cover.jpg`, and while chapters or extras folders might appear, they can confuse sorting in certain readers, and metadata like `ComicInfo.xml` or leftover files may also show up, but the core is an ordered list of images.
