Small Ko-fi tips help keep the converter free, fast, and private.
Comic page order preserved
Pages are sorted naturally, so 2.jpg appears before 10.jpg. This helps keep manga chapters and comic issues readable after export.
Flexible PDF layout
Use the original image size, fit pages to A4 or Letter, add a page border, fill each sheet, and control image clarity before downloading.
ZIP comic support
CBZ files are ZIP archives with comic images inside. You can also open ZIP archives that contain supported comic page images.

What is a CBZ file?
A CBZ file is a comic book archive. It is usually a ZIP file that contains a sequence of comic or manga page images, such as JPG, PNG, or WEBP files. Many comic readers can open CBZ directly, but some devices, document apps, e-readers, and sharing workflows work better with PDF.
This converter reads the archive in your browser, finds the supported image pages, sorts them in comic page order, and builds one PDF that you can download.
Why convert CBZ comics to PDF?
PDF is widely supported across phones, tablets, desktop computers, cloud drives, classroom tools, and e-readers. Converting CBZ to PDF can make a comic easier to open, share, print, archive, or read in apps that do not support comic archive formats.
For manga and comic collections, PDF is especially useful when you want one file that keeps pages together and opens reliably without a dedicated CBZ reader.
Private CBZ conversion, without uploading files
Many online file converters ask you to upload the original archive before they can process it. This tool is designed differently. The CBZ or ZIP file is opened in your browser, and the PDF is generated locally during your current session.
That means your comic pages are not sent to a remote conversion queue, and the generated PDF is not stored on our servers. Closing or refreshing the page clears the temporary previews and download link from the browser session.
Keep comic pages in the right order
Comic archives often name pages with numbers, such as 001.jpg, 002.jpg, and 010.jpg. The converter uses natural sorting so numbered pages stay in the expected reading order. For example, 2.jpg is placed before 10.jpg.
Before exporting, you can review the detected page previews. If the archive contains extra folders or macOS metadata files, the converter skips known non-page files so they do not become blank or broken pages in the PDF.
Supported comic archive and image formats
The converter supports CBZ files and ZIP archives that contain comic page images. Inside the archive, this version supports JPG, PNG, and WEBP pages. CBR files are not supported yet because CBR uses RAR compression, which needs different browser parsing support.
| Input | Status | Notes |
|---|---|---|
| .cbz | Supported | Best option for comic archives |
| .zip | Supported | Works when the ZIP contains comic image pages |
| JPG / JPEG | Supported | Embedded directly where possible |
| PNG | Supported | Embedded directly where possible |
| WEBP | Supported | Converted through canvas for PDF embedding |
| .cbr | Not yet supported | Uses RAR compression |
| Password-protected archives | Not supported | Browser cannot read encrypted contents in this version |
Choose the PDF layout that fits your reading device
Use image size when you want each PDF page to match the original comic page dimensions. Choose A4 or Letter when you need a standard document size for printing, sharing, or reading in document apps.
The page border option adds breathing room around each page. Fill page can make pages occupy more space on a standard PDF page, while image clarity controls the balance between visual quality and final file size.
Read converted comic PDFs on more devices
After conversion, the PDF can be opened in common document readers on Windows, macOS, iPad, iPhone, Android tablets, and many e-reader workflows. If you are preparing comics for a smaller screen, test one chapter first and compare original image size with A4 or Letter output.
For e-readers, page size and image clarity can affect readability and file size. A short test conversion helps you find the best setting before converting a large archive.
Before converting a large CBZ file
Large comic archives can require significant browser memory because the site needs to read images, create previews, and build the final PDF. Desktop browsers are usually more reliable than mobile browsers for very large books. If a large archive fails, try closing other tabs, using a desktop browser, lowering image clarity, or converting a smaller volume first.
Common CBZ to PDF conversion issues
If the converter cannot read an archive, the file may be damaged, encrypted, or not a ZIP-based CBZ file. If pages appear out of order, check whether the original file names use a consistent numbering pattern.
- Files such as ._001.jpeg are macOS metadata, not comic pages.
- Folders named __MACOSX store archive metadata and are skipped automatically when possible.
- Large archives may fail when the browser runs out of memory.
- CBR files use RAR compression and are not supported in this browser-only version.
Questions
Read the full FAQAre my CBZ files uploaded?
No. Conversion happens locally in your browser session. The site does not upload your CBZ archive or generated PDF to a conversion server.
Which files can I convert?
You can open CBZ files and ZIP archives that contain JPG, PNG, or WEBP comic page images.
Does the converter keep comic pages in order?
Yes. The converter uses natural sorting, so numbered pages such as 2.jpg and 10.jpg stay in the expected reading order.
Can I convert CBR files?
Not yet. CBR uses RAR compression, which needs a separate parser and heavier browser support.
Can I convert large comic archives?
Large archives can work, but browser memory is the limit. Desktop browsers are usually more reliable than mobile browsers for big books.
Can I use the PDF on Kindle or iPad?
The downloaded PDF can be opened in many document readers and e-reader workflows. For smaller screens, test one chapter first to compare page size and clarity settings.
