Free online CBZ to PDF converter

Source format: CBZ

CBZ is a comic book archive format. It is essentially a ZIP archive that contains a sequence of image files, usually .jpg, .jpeg, .png, and sometimes .webp or .avif. Comic readers, manga readers, and digital comic collectors use CBZ files because they preserve page order and are easy to organize.

Typical use cases include digital comics, scanned manga, webcomics, and archived page-based documents. Because CBZ is just a compressed container, it is convenient for storing many page images in one file.

Target format: PDF

PDF is a portable document format designed for reliable viewing and printing across devices and operating systems. It is widely supported by browsers, operating systems, office software, and dedicated readers.

PDF is a strong target for CBZ conversion because it keeps pages in a fixed order, is easy to share, and can be viewed on almost any device without special comic-reading software. It is also useful for printing, archiving, and annotating.

How to convert cbz to pdf

The best method depends on whether you want a quick conversion or more control over page size and compression.

Option 1: Use the built-in converter on 101convert.com

1. Open the CBZ to PDF conversion page on 101convert.com.
2. Upload your .cbz file.
3. Start the conversion.
4. Download the resulting .pdf file.

This is the simplest approach if you want to convert online for free without installing software.

Option 2: Use desktop software for more control

If you want to inspect or edit the pages before conversion, first extract the CBZ archive with a ZIP-compatible tool, then combine the images into a PDF using image or document software.

1. Open the .cbz file with an archive manager, or rename it to .zip if your tool requires that extension.
2. Extract the image files.
3. Open the extracted images in software that can export to PDF, such as Calibre, LibreOffice Draw, or a dedicated comic manager.
4. Check that the pages are in the correct order.
5. Export or save as PDF using File → Export As → Export as PDF or the equivalent menu in your software.

Option 3: Command-line conversion with ImageMagick

If your CBZ contains standard image pages, you can extract the archive and convert the images into a PDF. Example workflow:

1. Extract the CBZ contents.
2. Run a command such as magick *.jpg output.pdf or magick *.png output.pdf, depending on the image format.

For mixed image types, you may need to convert or rename files so they sort in the correct page order before creating the PDF.

Notes on quality, compatibility, and limitations

Image quality is usually preserved because CBZ pages are already raster images. However, the final PDF quality depends on the resolution and compression of the original images.

Page order matters. If filenames are not numbered consistently, pages may appear out of sequence during conversion. Make sure the images are named in a natural reading order such as 001.jpg, 002.jpg, and so on.

CBZ is not a text-based format, so converted PDFs usually do not contain selectable text unless OCR is applied separately.

Large comics can produce large PDFs, especially if the source images are high resolution or lightly compressed. If file size is important, consider resizing or recompressing images before creating the PDF.

Compatibility is excellent for PDF, but some comic-specific features such as panel view, reading direction, or metadata may not carry over perfectly. If those features matter, keep the original CBZ as well.
