Inside the CBZ - Understanding the Anatomy of Digital Comics
Last Updated: 28 July, 2026
TL;DR
CBZ (Comic Book Zip) is nothing more than a standard ZIP archive that bundles a series of sequential image files—plus optional metadata—into a single, DRM‑free comic container. Because it relies on the ubiquitous ZIP format, any archiving tool can open it, and readers simply sort the images alphabetically to display pages in order. Modern CBZs often include ComicInfo.xml for rich library data, use efficient image codecs like WebP/AVIF, and even embed HTML for interactive “enhanced” comics.
