A CBZ file serves as a ZIP archive of page images, built from page images labeled in strict numeric order to display correctly, sometimes paired with metadata or extras, and readers show it like an actual comic with bookmarking or two-page spreads; you can open or extract it by renaming it to `.

A CBZ file being "a ZIP file with a comic label" indicates the archive remains a standard ZIP beneath the new name, enabling readers to display ordered images like a comic, while tools like 7-Zip can still open it because the underlying format hasn’t changed; renaming it to .zip simply switches which application your system chooses to use by default.

A CBZ and a ZIP are treated differently solely because of their suffix, 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 usually the one that gives you the least hassle, 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 finding and ordering its image files, ignoring metadata, sorting the pages alphabetically to determine reading order, then decompressing pages on demand into temporary storage so flips are quick, rendering them with your chosen view mode and enhancements, and recording your page progress and cover image for smoother library browsing.

Inside a CBZ file you typically find a compressed bundle of sequential images, most commonly JPG/JPEG with some PNG or WEBP pages, arranged in filename order (`001.jpg`, `002.jpg`, etc.); there may be a dedicated cover image, occasional subfolders that some readers sort oddly, and optional metadata or leftover files, but the core idea is a tidy stack of image pages for reading apps to present.
