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
- Upload a PDF by clicking the drop zone or dragging a file onto it.
- Choose image format, quality, scale, and optional metadata.
- Click Convert to generate the CBZ file.
- The
.cbzfile 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.
