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.

A CBZ file being “a ZIP file with a comic label” means it’s structurally identical to a .zip archive, with the .cbz extension telling devices to open it in comic-reading mode rather than as a generic archive; because of this, CBZ isn’t a proprietary format but a naming convention, and the images inside—usually numbered pages—can be extracted by renaming the file to .zip or opening it directly in tools like 7-Zip, proving the real difference is how software chooses to treat it.
A CBZ and a ZIP can contain identical image sequences, with .cbz telling comic apps to present the content as ordered pages and .zip signaling a general archive; CBZ’s ZIP foundation ensures maximum compatibility, while its siblings—CBR (RAR), CB7 (7z), and CBT (TAR)—store images the same way but may have reduced support depending on compression type and platform.
In real-world terms, the “best” format is whichever your reader supports most consistently, making CBZ the most universal choice, though CBR/CB7/CBT are fine when supported; converting to CBZ is straightforward since it’s just ZIP underneath, and comic apps open CBZ files as page sequences with reading tools—unlike archive apps, which only show files for extraction.
A comic reader app “reads” a CBZ by pulling pages from the archive in sorted order, identifying image files as pages, sorting them (often by zero-padded names), then decoding and caching only the ones you view so performance stays fast without extracting everything, while applying viewing preferences and saving your reading position plus a thumbnail for library organization.
Inside a CBZ file you typically find a compiled set of page images meant for readers, 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.xml` or stray extras might be present, yet the essential structure remains a straightforward, well-ordered image sequence inside one archive.
