# PDF to CBZ
|
|||
|
|
|
|||
|
|
Converts a PDF into a CBZ (Comic Book ZIP) file — the standard format for digital comics and manga. Each PDF page becomes an image inside the archive. The tool generates metadata in three formats for maximum compatibility: ComicInfo.xml, metadata.opf, and ComicBookInfo JSON.
|
|||
|
|
|
|||
|
|
## How It Works
|
|||
|
|
|
|||
|
|
1. Upload a PDF by clicking the drop zone or dragging a file onto it.
|
|||
|
|
2. Choose image format, quality, scale, and optional metadata.
|
|||
|
|
3. Click **Convert** to generate the CBZ file.
|
|||
|
|
4. The `.cbz` file downloads automatically.
|
|||
|
|
|
|||
|
|
## Options
|
|||
|
|
|
|||
|
|
| Option | Values | Default | Description |
|
|||
|
|
| ---------------- | --------------- | ------- | ----------------------------------------------------------------------------- |
|
|||
|
|
| Image Format | JPEG, PNG, WebP | JPEG | JPEG for color comics, PNG for lossless B&W manga, WebP for best compression. |
|
|||
|
|
| Quality | 50–100% | 85% | Controls JPEG/WebP compression. Hidden for PNG (always lossless). |
|
|||
|
|
| Scale | 1.0x–4.0x | 2.0x | Higher scale produces sharper images for high-res screens. |
|
|||
|
|
| Grayscale | On/Off | Off | Converts pages to grayscale. Reduces file size for B&W content. |
|
|||
|
|
| Manga mode | On/Off | Off | Sets right-to-left reading direction in metadata. |
|
|||
|
|
| Include metadata | On/Off | On | Embeds ComicInfo.xml, metadata.opf, and ComicBookInfo JSON. |
|
|||
|
|
|
|||
|
|
## Metadata Fields
|
|||
|
|
|
|||
|
|
When metadata is enabled, you can fill in:
|
|||
|
|
|
|||
|
|
- **Title** — Auto-detected from the PDF filename.
|
|||
|
|
- **Series** — The series name (e.g., "Naruto").
|
|||
|
|
- **Number (#)** — Issue number within the series.
|
|||
|
|
- **Volume (Vol.)** — Volume number.
|
|||
|
|
- **Author(s)** — Writer or creator name.
|
|||
|
|
- **Publisher** — Publishing company.
|
|||
|
|
- **Tags / Genre** — Comma-separated tags (e.g., "Action, Adventure").
|
|||
|
|
- **Published Year** — Year of publication (1900–2100).
|
|||
|
|
- **Rating** — Community rating from 0 to 5.
|
|||
|
|
|
|||
|
|
## Metadata Compatibility
|
|||
|
|
|
|||
|
|
The tool writes metadata in three formats so every reader can find it:
|
|||
|
|
|
|||
|
|
| Format | Location | Supported by |
|
|||
|
|
| ------------------ | ----------------- | ------------------------------------------- |
|
|||
|
|
| ComicInfo.xml | File inside ZIP | Komga, Kavita, CDisplayEx, Mylar, ComicRack |
|
|||
|
|
| metadata.opf | File inside ZIP | Calibre |
|
|||
|
|
| ComicBookInfo JSON | ZIP comment field | Calibre (fallback) |
|
|||
|
|
|
|||
|
|
## Output Format
|
|||
|
|
|
|||
|
|
- `filename.cbz` — A ZIP archive containing numbered page images and metadata files.
|
|||
|
|
|
|||
|
|
Page images are named with zero-padded numbers (`01.jpg`, `02.jpg`, etc.) so readers display them in the correct order.
|
|||
|
|
|
|||
|
|
## Use Cases
|
|||
|
|
|
|||
|
|
- Converting manga or comic PDFs for use with comic book readers.
|
|||
|
|
- Building a digital comic library in Komga, Kavita, or Calibre.
|
|||
|
|
- Converting scanned comic books to a reader-friendly format.
|
|||
|
|
- Sharing comics in a format that preserves reading direction and metadata.
|
|||
|
|
|
|||
|
|
## Tips
|
|||
|
|
|
|||
|
|
- Use **JPEG** for color comics and **PNG** for black-and-white manga — PNG compresses B&W content very efficiently.
|
|||
|
|
- Enable **Grayscale** for manga to significantly reduce file size.
|
|||
|
|
- Fill in the **Series** and **Number** fields so library managers (Komga, Calibre) can organize your collection automatically.
|
|||
|
|
- **WebP** offers the best compression but older comic readers may not support it.
