About the CBZ Format

CBZ stands for Comic Book ZIP: page images, normally JPEG or PNG, sitting in an ordinary ZIP archive under a different extension. Because ZIP is openly specified and every operating system can already read it, CBZ became the format comic readers and digital libraries standardised on. Rename a CBZ to .zip and it opens in your file manager: the pages are just files, in order, with nothing proprietary in the way.

CBZ also carries the closest thing the format family has to metadata. ComicInfo.xml, a convention introduced by ComicRack rather than any standards body, sits alongside the images and records series, issue number, writer, artist and publication year. Readers that understand it build a browsable library from your files; readers that do not simply ignore the extra file. It is worth preserving when you reorganise a collection, because regenerating it by hand is tedious.

The thing to know before converting is that a CBZ is a book of pictures, not text. There are no words for a device to reflow, so converting to EPUB only works as fixed-layout EPUB, and an eReader without that support will render it poorly or not at all. PDF is the more dependable target when you need to read or print a comic outside a dedicated app, though it usually produces a larger file. Either way the page images are carried across at their original resolution and quality.

Frequently asked questions

Will chapters and the table of contents survive conversion?

The text itself converts without loss, because ebook formats store markup rather than pixels. Structure is the fragile part, each format handles chapter breaks, the table of contents, embedded fonts and CSS differently, so expect styling to shift and check the contents page afterwards. Images carry across unchanged, and files with DRM cannot be converted at all.

What is the maximum file size for CBZ conversion?

Free users can convert CBZ files up to 100 MB. Pro raises that to 1 GB and Business to 2 GB.
