HTML → CBZ/CBR
Going from HyperText (.html, .htm, .xhtml, .xml, .mhtml) to Comic book archive (.cbr, .cbz, .cbt, .cb7) is a routinely useful direction for this kind of file — a comic archive is a page-ordered image bundle that comic readers page through properly. Going from HyperText to Comic book archive does raise extra questions worth thinking about: you lose adjustable font size and screen-based reflow; the searchable, copyable text layer. Below we explain in detail how HyperText becomes Comic book archive and what to watch out for, and the page ends with a converter that does the job right in your browser — nothing is uploaded, the file never leaves your machine.
What is HTML?
HTML and XHTML are the structural languages of the web, and XHTML is also what EPUB uses internally to hold its content — so converting between HTML and EPUB is essentially a matter of swapping the shell and how assets are packaged. .mhtml goes further and packs a page together with its images and styles into one file, which suits preserving online pages that may disappear. HTML's strength is that it is universal and opens in any browser; its weakness is that styles and images are usually external links, so shipping one self-contained file means inlining them first.

| Extensions | .html.htm.xhtml.xml.mhtml |
|---|---|
| Typical use | Captured web content, EPUB internal content, and a general intermediate representation for other formats. |
What is CBZ/CBR?
A comic archive (.cbz, .cbr, .cbt, .cb7) is really just a set of one-image-per-page files packed into an archive under a different extension: .cbz is ZIP, .cbr is RAR, .cbt is TAR and .cb7 is 7z. It has no text layer, so it can be neither searched nor copied, and page order comes entirely from how filenames sort — which means the names must be zero-padded (001.jpg, 002.jpg) or page 10 lands right after page 2. It suits comics, art books and page-scanned volumes: it is a collection of images, not a text book. Read the CBZ/CBR format guide
| Extensions | .cbr.cbz.cbt.cb7 |
|---|---|
| Typical use | Comics, art books and books scanned to images; fundamentally an image bundle rather than a text book. |
How to convert HTML to CBZ/CBR
All structure lives in the tags, but real pages mix in navigation, ads and footers that a naive conversion carries along. Extract the content container first (a readability pass), and note that <img> usually points outside the file — images must be downloaded and embedded before producing a single-file format.
Converting to a comic archive really just packs images under ordered names; all text is discarded. Zero-pad the filenames (001.jpg, 002.jpg) so sorting works, and note that .cbr needs RAR tools while most readers handle .cbz (ZIP) best.
Reflow is lost: the target freezes the layout, so readers can no longer change font size or line width. Long novels become zoom-and-pan on small screens — the most common reason a conversion ends up harder to read. Unless you need print or layout-critical delivery, keep a reflowable copy for reading.
The target is image-only: all text in the source is discarded (or survives only as pixels). If your goal is content that can be searched, copied or read aloud, this direction is wrong — pick a text-preserving target instead.
Going from a single text file to a structured archive adds information: the tool must generate the manifest, the navigation document and metadata for you. The quality of those generated parts — accurate chapter splitting, correct language tags — decides whether the result is usable.
