How to Convert CBZ to PDF

CBZ (Comic Book ZIP) files are ZIP archives containing sequential image files — typically JPG or PNG. While dedicated comic reader apps open CBZ, many e-readers, tablets and PDF apps don't. Converting CBZ to PDF embeds each page image into a PDF, giving you universal compatibility.

FormatDrop doesn't convert CBZ to PDF yet. The methods below use free tools that do. FormatDrop's own converters cover common image, audio, video and PDF formats, all in your browser.

Other ways to convert CBZ to PDF

  1. 1

    Calibre (free, Windows, Mac, Linux)

    Add the CBZ to Calibre, select it and click Convert books. Set the output format to PDF and click OK. The Comic input section of the convert dialog can also grayscale or resize pages for e-ink readers.

  2. 2

    ImageMagick (command line)

    Unzip the pages, then join them: `unzip input.cbz -d pages && magick pages/*.jpg output.pdf`. Check the page order first: the shell sorts page10.jpg before page2.jpg unless the numbers are zero-padded (page02.jpg).

  3. 3

    img2pdf (lossless)

    img2pdf puts JPG pages into a PDF without re-compressing them: `unzip input.cbz -d pages && img2pdf pages/*.jpg -o output.pdf`. Install with `pip install img2pdf`.

  4. 4

    Send it to your reader

    Copy the PDF to a Kobo or iPad, or use Send to Kindle. Big comic PDFs can turn pages slowly on e-ink readers; a CBZ in a comic reader app is often smoother.

Why convert CBZ to PDF?

CBZ is the comic enthusiast's format; PDF is the format that everything reads. Converting CBZ to PDF makes your comic library accessible on every device without a dedicated reader app.

Frequently asked questions

How do I convert CBZ to PDF on the command line?
Unzip the CBZ, then join the pages with ImageMagick: `unzip input.cbz -d pages && magick pages/*.jpg output.pdf` (older ImageMagick: `convert` instead of `magick`). img2pdf does the same without re-compressing the JPGs: `img2pdf pages/*.jpg -o output.pdf`.
Will the page order be correct in the PDF?
Yes, if the images are numbered sequentially (001.jpg, 002.jpg, …). Most CBZ files use zero-padded numbering, which sorts correctly. If pages come out of order, sort them numerically before concatenation.
Can I convert CBR (Comic Book RAR) to PDF the same way?
The process is identical, but you need to unrar the CBR first: `unrar e input.cbr pages/`. Then convert the extracted images to PDF. CBR is a RAR archive; CBZ is a ZIP archive — both contain the same page images.
