CBZ to PDF
Turn comic book archive files into PDFs. CBZ and CBR are the standard formats for digital comics -- they are just ZIP or RAR archives filled with images. This tool extracts each page, preserves the reading order, and produces a clean PDF where every image becomes a full-size page.
Supported Formats
| Format | Extension | Notes |
|---|---|---|
| CBZ | .cbz | ZIP-based comic archive (processed locally with pdf-lib) |
| CBR | .cbr | RAR-based comic archive (processed via PyMuPDF engine) |
The CBZ converter recognizes JPEG, PNG, GIF, BMP, WebP, AVIF, TIFF, HEIC, and JXL images inside the archive. Non-standard formats are auto-converted to PNG before embedding.
How It Works
- Click the upload area or drag and drop your CBZ or CBR files. You can mix both formats in a single batch.
- Review the listed files. Remove any you don't need, or click Add More Files to add more.
- Click Convert to PDF. For CBZ files, the tool unzips the archive, sorts image files by name in natural order, detects each image's actual format, and embeds them into a PDF using pdf-lib. CBR files are routed through the PyMuPDF engine instead.
- A single file downloads as a PDF. Multiple files produce a ZIP archive named
comic-converted.zip.
Options
No configuration is required. Each image becomes a page sized to match its original dimensions, so double-page spreads stay wide and single pages stay narrow.
Use Cases
- Reading comics on a tablet or phone app that supports PDF but not CBZ/CBR
- Printing specific pages from a digital comic
- Archiving a comic collection into a format any file viewer can open
- Sharing a comic with someone who does not have a dedicated comic reader
Tips
- Images inside the archive are sorted using natural ordering (so
page2.jpgcomes beforepage10.jpg). Name your files with consistent numbering for correct page sequence. - The converter detects image formats by their binary signatures, not file extensions. A PNG accidentally named
.jpgwill still embed correctly. - CBZ files are processed entirely in the browser without loading the PyMuPDF engine, so they convert faster than CBR files.
