What is a CBZ File?
A CBZ file is a digital comic book format that uses ZIP compression to store sequential images. Think of it as a digital comic book where each page is an individual image file (JPG, PNG, etc.) packed together in a specific order. The "CBZ" stands for "Comic Book ZIP."
Key Characteristics of CBZ Files:
- • Uses standard ZIP compression for universal compatibility
- • Contains sequential images representing comic pages
- • Supported by most digital comic readers
- • Easy to create and modify compared to proprietary formats
- • Maintains image quality while reducing file size

Getting Started with CBZ Creation
What You'll Need
Required Materials:
- Sequential Images: Your comic pages in JPG, PNG, GIF, or WebP format
- Consistent Naming: Pages named in order (page001.jpg, page002.jpg, etc.)
- CBZ Editor: Our online tool or desktop software
Image Preparation Tips
✅ Best Practices
- • Use consistent image dimensions
- • Maintain 300 DPI for print quality
- • Save images in RGB color mode
- • Use JPG for photos, PNG for graphics
- • Keep file sizes reasonable (under 5MB per page)
❌ Avoid These
- • Mixing different aspect ratios
- • Using extremely large file sizes
- • Inconsistent image quality
- • Missing or duplicate pages
- • Special characters in filenames
Step-by-Step Creation Process
Upload Your Content
Start by uploading your comic pages or existing comic files to the CBZ editor.
- • Individual Images: Upload JPG, PNG, GIF, WebP files
- • Existing Comics: Upload CBR or CBZ files to edit
- • Batch Upload: Select multiple files at once
- • Drag & Drop: Simply drag files into the upload area
The editor automatically detects file types and sorts images by filename. For best results, name your files sequentially (page001.jpg, page002.jpg, etc.).
Organize Your Pages
Use the visual interface to arrange your pages in the correct reading order.
- • Drag & Drop: Click and drag pages to reorder them
- • Visual Preview: See thumbnails of each page
- • Page Numbers: Automatic numbering shows current order
- • Real-time Updates: Changes are applied instantly
Consider your comic's reading direction. Western comics typically read left-to-right, while manga reads right-to-left. Arrange pages accordingly.
Set Your Cover Thumbnail
Choose which page will represent your comic as the cover image. The selected page automatically moves to position 1 to ensure it becomes the thumbnail.
- • Click the crown icon on any page to set it as cover
- • The page automatically moves to position 1 (first page)
- • Gets a special yellow border and crown badge indicator
- • Becomes the thumbnail in comic readers and file explorers
- • Other pages shift position to accommodate the new cover
CBZ files use the first page as the thumbnail in most comic readers. By automatically moving your chosen cover to position 1, the editor ensures your selection is respected across all reading platforms.
Add Comic Metadata (Optional)
Add professional metadata that will be included as ComicInfo.xml in your CBZ file for better organization and compatibility.
- • Title & Series: Comic title and series name
- • Issue & Volume: Number identification
- • Publisher: Publishing company or creator
- • Genre: Superhero, Action, Horror, etc.
- • Writer & Penciller: Creative team credits
- • Publication Date: Month and year

Common Issues & Solutions
❌ Problem: Pages appear in wrong order
Solution: Use the drag-and-drop interface to manually reorder pages. The editor shows page numbers to help you get the sequence right.
Prevention: Name your source images with leading zeros (page001.jpg, page002.jpg).
⚠️ Problem: CBZ file is too large
Solution: Optimize your source images before creating the CBZ. Reduce resolution or compress images while maintaining readability.
Tip: For web distribution, aim for under 100MB total file size.
⚠️ Problem: Cover doesn't appear correctly
Solution: Use the crown icon to explicitly set which page should be the cover. Some readers use the first page, others use designated thumbnails.
Best Practice: Always set a cover thumbnail manually for consistency.
ℹ️ Problem: Reader doesn't support CBZ
Solution: CBZ files are standard ZIP files. You can often rename the .cbz extension to .zip and extract the images manually.
Alternative: Use our converter tools to create PDF or EPUB versions.
