How to convert PDF to CBZ online
Each PDF page is rendered in the browser, named with zero-padded page numbers, and compressed into a ZIP-based CBZ archive.
Choose PDF files
Add up to 10 PDF files, each no larger than 250 MB or 500 pages.
Choose page resolution
Use 72 DPI for smaller archives, 144 DPI for balanced reading, or up to 300 DPI for detailed pages.
Download CBZ
The browser renders ordered PNG pages and packages them in a downloadable .cbz file.
PDF to CBZ resolution and output
Resolution controls page sharpness and archive size. The output remains a standard CBZ containing PNG files.
| Control | Setting | Effect |
|---|---|---|
| Resolution | 72, 144, 216, or 300 DPI | Balances sharpness, conversion time, memory, and archive size |
| Image format | Lossless PNG | Avoids JPEG artifacts when PDF pages contain text or line art |
| Page naming | Zero-padded numbers | Keeps page order stable in comic reader apps |
| File handling | Local browser | The source PDF and rendered pages never leave the device |
PDF vs CBZ for digital comics
PDF stores composed document pages; CBZ stores a sequence of image files that comic readers can navigate.
| Characteristic | Source | Output |
|---|---|---|
| Structure | Document page objects | ZIP archive of page images |
| Text | May remain selectable | Flattened into page pixels |
| Page quality | Vector or embedded source content | Rasterized at the selected DPI |
| Comic readers | Broad but document-focused | Designed for sequential comic navigation |
| Metadata | May include author and document fields | This output contains ordered PNG pages only |
Create a clean CBZ comic archive
The generated archive contains only ordered PNG pages. It does not add watermarks, tracking files, or source document metadata.
Every page is included
The converter exports the complete PDF in source order, up to the stated 500-page safety limit.
PNG favors line art
Lossless encoding keeps speech bubbles, lettering, and sharp manga lines free of new JPEG blocks.
Higher DPI needs more memory
A 300 DPI conversion creates far more pixels than 72 or 144 DPI and is best suited to desktop browsers.
Text becomes pixels
CBZ pages are images, so selectable PDF text, links, forms, and annotations are flattened into the rendered page.

The reverse CBZ to PDF workflow preserves existing archive images and therefore belongs on its own focused page.
PDF to CBZ converter FAQ
How do I convert PDF to CBZ?
Choose a PDF, select a render resolution, click Convert to CBZ, and download the archive. No desktop software or account is required.
Is a CBZ file just a ZIP file?
Yes. CBZ is a ZIP archive that contains sequential comic page images. The .cbz extension tells comic reader software how to handle it.
Are PDF files uploaded to a server?
No. PDF rendering, PNG encoding, ZIP compression, and download run locally in your browser.
Which DPI should I choose?
Use 144 DPI for a practical balance. Choose 72 DPI for smaller files, 216 DPI for sharper screens, or 300 DPI when print detail matters and memory is available.
Will PDF text remain selectable in CBZ?
No. Each PDF page is rendered to a PNG image, so text, links, forms, layers, and annotations become pixels.
Does the CBZ preserve page order?
Yes. Files are named page-001.png, page-002.png, and so on, with enough zero padding for the document length.
Can I batch convert PDF to CBZ?
Yes. Add up to 10 PDFs and download the resulting CBZ files individually or together in a ZIP.
Why is my CBZ larger than the PDF?
PDFs may reuse fonts, vectors, or compressed images. A CBZ stores a full PNG rendering of every page, so higher DPI output can be much larger.
What are the limits?
Each PDF can be up to 250 MB and 500 pages. A rendered page is limited to 50 megapixels, and high-DPI conversion may exceed mobile browser memory sooner.
