Some comic-reading apps accept CBZ archives but not MOBI ebooks. Converting a MOBI book to CBZ renders its pages as images, so the result is suited to fixed-page reading rather than adjustable text.
What the MOBI format is
MOBI is an ebook format used by older Amazon Kindle devices and software, and by Mobipocket readers. MOBI files may contain reflowable text, images, and formatting; Calibre can create or convert MOBI files, and older Kindle or Mobipocket libraries are common sources. Some MOBI files have DRM, which can prevent conversion.
What the CBZ format is
CBZ is a ZIP archive of page images, commonly used for digital comics and graphic novels. Comic readers display its images in filename order. It works well for fixed-layout pages, but it does not preserve selectable text, ebook reflow, or most ebook navigation and formatting.
How to actually convert MOBI to CBZ
Online on 101convert.com
- Open the MOBI-to-CBZ converter on 101convert.com and upload the file.
- Choose CBZ as the output format and start the conversion.
- Download the converted CBZ file when processing is complete.
The page supports batch conversion, with a per-file size limit shown on the page.
Offline with desktop software
Calibre, ImageMagick, and 7-Zip provide a free desktop workflow on Windows, macOS, and Linux. First convert the ebook to PDF, then render the PDF pages as image files and archive them as CBZ.
- Use Calibre’s command-line converter:
ebook-convert input.mobi book.pdf. - With ImageMagick installed and PDF reading enabled, render the pages:
magick -density 150 book.pdf -quality 90 page-%04d.jpg. Increase or decrease150to change the rendering resolution. - From the folder containing the images, create the archive with 7-Zip:
7z a book.cbz page-*.jpg. The numbered filenames keep the pages in order.
ImageMagick may require Ghostscript to read PDFs. If the MOBI is DRM-protected, use a copy you are permitted to convert; the workflow cannot remove DRM.
Quality and limitations
CBZ pages are raster images, so the output can be larger than the original and text will not reflow or remain searchable. Resolution and JPEG quality affect readability and file size; inspect small text and images before archiving. The conversion also depends on the PDF layout and fonts produced by Calibre.
