How to Make
a CBZ File
Complete step-by-step guide to creating CBZ (Comic Book ZIP) files from your images. Learn the easiest methods and free tools for making professional comic book archives.
What is a CBZ File?
CBZ (Comic Book ZIP) is a compressed archive format designed for digital comics. It's essentially a standard ZIP file containing image files (JPG, PNG, GIF) with a .cbz extension that comic book reader applications recognize and display in proper reading order.
Method 1: Online Images to CBZ Converter (Recommended)
Prepare Your Images
Organize your comic book images and name them numerically for proper page order:001.jpg,002.jpg,003.jpg, etc.
Upload to Online Converter
Use our free Images to CBZ converter. Simply drag and drop all your comic images into the upload area. The tool supports JPG, PNG, GIF, and BMP formats.
Create CBZ Archive
Click "Create CBZ Comic" and the tool will automatically sort your images by filename and package them into a professional CBZ file ready for download.
✅ Why This Method is Best:
- • No software installation required
- • Automatic filename sorting
- • Works on any device
- • 100% free to use
- • Files never leave your device (client-side processing)
Method 2: Using Windows Built-in ZIP
Select Your Images
In Windows Explorer, select all your comic book images. Make sure they're properly named in numerical order for correct page sequence.
Create ZIP Archive
Right-click on the selected images and choose "Send to" → "Compressed (zipped) folder". This creates a ZIP file with all your images.
Rename to .cbz Extension
Rename the created ZIP file by changing the extension from .zipto .cbz. For example:MyComic.zip →MyComic.cbz
Method 3: Using 7-Zip (Advanced Users)
Download and Install 7-Zip
Download 7-Zip from the official website (7-zip.org) and install it. 7-Zip is free and provides better compression options than Windows built-in ZIP.
Create Archive with Compression
Right-click your selected images and choose "7-Zip" → "Add to archive...". Set format to "zip", choose compression level, and create the archive.
Rename to CBZ
Change the file extension from .zip to .cbz to make it recognizable by comic book readers.
Best Practices for CBZ Creation
- Proper Naming: Use zero-padded numbers (001, 002, 003) to ensure correct page order
- Image Quality: Use high-resolution images (at least 1200px width) for better reading experience
- File Size Balance: Optimize images to balance quality and file size
- Supported Formats: JPG for photos/colored pages, PNG for text-heavy or black & white pages
- Testing: Always test your CBZ file in a comic reader before sharing
