How to convert CBZ to EPUB

A CBZ is a comic book archive — really just a ZIP full of page images — and most e-readers won't open it directly. Converting CBZ to EPUB wraps those pages in a proper e-book so it shows up in your library with a cover, correct page order, and native page-turning. This converter runs entirely in your browser, so your comic is never uploaded to a server.

  1. Choose your CBZ file above. The tool reads it locally and lists the pages it found so you can confirm the order.
  2. Keep "Fixed-layout" selected for comics and manga — it preserves each page as a full image at its original size, exactly as drawn.
  3. Add a title and author (optional) so the book is easy to find on your device. The first page is used as the cover unless you turn that off.
  4. Convert and download the EPUB. That's it — open it in any e-reader, or use Send to Kindle to read it on a Kindle.

What is a CBZ file, and why convert it to EPUB?

CBZ (Comic Book ZIP) stores scanned or exported comic pages as ordered JPEG or PNG images inside a ZIP archive. It's popular because it's simple, but that simplicity is also its weakness: phones, tablets, and e-ink readers treat it as a plain archive rather than a book. EPUB is the open e-book standard those devices understand natively, so converting CBZ to EPUB gets you a real reading experience — a cover, a library entry, bookmarks, and smooth page navigation — without re-compressing or degrading a single image.

Read CBZ comics on Kindle

To read a CBZ comic on Kindle, convert it to a fixed-layout EPUB here, then add the file with Send to Kindle (via the web uploader, the desktop app, or your personal @kindle.com email). Amazon converts fixed-layout EPUBs into the Kindle comic format on delivery, keeping every page sharp and in order. Fixed-layout is the right choice for comics because it locks the artwork to the page instead of reflowing it like a novel.

Converting CBR to EPUB

Looking to convert CBR to EPUB? CBR archives use the RAR format, which can't be unpacked in the browser without heavy extra libraries, so this tool works with CBZ only. The fix is quick: open the CBR in a tool like 7-Zip, WinRAR, or an archive app, extract the images, and re-zip them as a .cbz (or rename the extracted ZIP). Then drop that CBZ here to get your EPUB. The page images are copied byte-for-byte, so nothing is lost in the round trip.

Manga and right-to-left comics

For Japanese manga — or Arabic and Hebrew comics — pick a matching language and enable right-to-left page progression. That flips the reading direction so page turns and two-page spreads flow the way the artist intended, instead of jumping backward. Combined with fixed-layout and EPUB 3, it produces a manga file that reads naturally on any modern e-reader.

Frequently Asked Questions

No. The file is opened locally in your browser; nothing is uploaded.

A CBZ is just a ZIP archive containing comic page images (usually JPEG or PNG). Renaming it to .zip shows the same content.

No — only CBZ. CBR uses the RAR format and CB7 uses 7-Zip; both require additional libraries this tool doesn't bundle. If you have CBR, repack it as CBZ first.

By filename inside the archive, ascending (natural sort). Most CBZ files use predictable names like 001.jpg, 002.jpg, etc.

Yes. Download the EPUB and use Send to Kindle. Amazon converts fixed-layout EPUBs for Kindle readers and apps.

No. Page images are copied byte-for-byte from the CBZ into the EPUB, preserving original quality and size.

Pick a manga-friendly language and use EPUB 3. Right-to-left page progression makes panel order feel natural for Japanese manga and Arabic/Hebrew comics.
