CBZ/CBR → HTML
Going from Comic book archive (.cbr, .cbz, .cbt, .cb7) to HyperText (.html, .htm, .xhtml, .xml, .mhtml) is a routinely useful direction for this kind of file — HTML opens in any browser and embeds easily into a web page. Fortunately Comic book archive and HyperText are structurally close, so there is not much to lose. Below we explain in detail how Comic book archive becomes HyperText 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 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. |
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. |
How to convert CBZ/CBR to HTML
A comic archive is a renamed archive: .cbz=ZIP, .cbr=RAR, .cbt=TAR, .cb7=7z. It has no text layer, and page order comes from filename sorting — if names are unpadded (1.jpg, 2.jpg … 10.jpg) page 10 lands right after page 2, so rename with zero padding first.
Whether images and styles are linked or embedded decides if the result travels as one file. To ship a single file, inline the assets as data URIs or use MHTML; otherwise moving the file breaks the images. Keep semantic tags (h1–h6, p) so a later EPUB conversion still yields a table of contents.
Layout must be rebuilt: the paragraph, column and figure positions in the source were arranged for a fixed page and mean nothing once the target reflows. The converter can only re-stitch a text stream, so paragraphs may merge wrongly, columns may interleave and figures may land mid-sentence. Read the first few chapters afterwards, watching dialogue breaks and figure placement.
The source has no text layer — every page is an image. No text-targeted conversion can conjure text: you either get blank output or the image inserted as one oversized object. Getting searchable, reflowable text requires OCR first, and OCR on Chinese fiction introduces character errors that need proofreading.
The source is one full-page image per page while the target reflows: each image is inserted in sequence, and with no text layer you end up with an image stream. The result is usually huge and unsearchable — a worse reading experience than the original.
