Key Features

CBR and CBZ Support

Convert both CBR and CBZ comic book archives from the same tool. The container is detected from the file header, so a ZIP renamed to .cbz still works.

Natural Page Ordering

Sort numbered image files in reading order, so page2 comes before page10. The preview shows the exact order the PDF will use.

Preserve Aspect Ratio

Fit comic pages to the selected PDF layout without stretching or unwanted cropping. Fit to image keeps each page's original proportions.

Preview Pages

Preview the detected comic pages before creating the PDF and check their order, including the thumbnails read straight from the archive.

Reading Direction

Choose left-to-right or right-to-left reading direction for comics and manga. Right to left reverses the page order in the PDF itself, so it reads correctly in any viewer.

PDF Export

Create a fixed-layout PDF for reading, sharing, archiving, or printing — built locally in your browser with pdf-lib.

How to Use

1

Add a CBR or CBZ File

Drag and drop or select a comic archive. The archive is opened locally in your browser and never uploaded.

2

Check the Page Order

Review the detected pages and their order. Files are sorted naturally, so page2 comes before page10. Archive metadata such as ComicInfo.xml is not turned into a page.

3

Choose Layout and Direction

Pick fit to image, A4, or Letter, set orientation, margins, and background, and choose right-to-left if you are converting manga.

4

Convert and Download

Run the tool to build the PDF, then download it. Any skipped or rescaled pages are listed in the report on the results page.

CBR & CBZ to PDF Example

A 128-page CBZ manga volume is converted to a 128-page PDF with fit-to-image pages and right-to-left order.

Comic archive
manga-vol-01.cbz (page-001.jpg … page-128.jpg)

A ZIP-based comic archive holding one JPG per page, named with zero-padded numbers.

PDF
manga-vol-01-minopdf.pdf (128 pages)

One PDF page per image, in natural order, at each page's own aspect ratio.

How to Convert CBR and CBZ to PDF

How to Convert CBR and CBZ to PDF

CBR and CBZ files are comic book archives containing ordered page images. This tool extracts the supported images, keeps their reading order, and places each image on a separate PDF page — all locally in your browser.

How to Convert a Comic Archive to PDF

  1. Add a CBR or CBZ file.
  2. Let the tool scan the archive and find supported page images.
  3. Review the page order and preview.
  4. Choose fit-to-image, A4, Letter, or another supported layout, plus the reading direction.
  5. Generate and download the PDF.

What Is the Difference Between CBR and CBZ?

CBR usually uses a RAR archive, while CBZ usually uses a ZIP archive. Both formats normally contain a sequence of JPG, PNG, or other image files that represent comic pages. Neither is an image format of its own, which is why this tool identifies the container from the file header rather than trusting the extension.

How Page Order Works

The converter uses natural numeric sorting so files such as page1, page2, and page10 appear in the expected order. Plain alphabetical sorting would place page10 before page2, which is the most common way comic conversions go wrong. Review the preview if the archive contains unusual filenames, multiple folders, duplicate numbers, or special cover files.

Fit Comic Pages Without Cropping

Fit-to-image output keeps the original aspect ratio and is usually the best choice for comics and manga. A4 and Letter layouts are more suitable for printing, but they may add margins around pages that do not match the paper ratio.

Reading Direction for Manga

Manga is read right to left. Choosing that direction reverses the page order in the finished PDF, so the last page of the archive becomes the first page of the document and the story opens correctly in any viewer. The images themselves are untouched.

CBR and CBZ Limitations

  • Password-protected archives are not supported.
  • Split or multi-volume archives must be joined first.
  • Very large archives may use significant browser memory, and RAR (CBR) archives have stricter size limits than CBZ. Instead of refusing, the tool scales pages down to a readable size, and if the result still does not fit in one file it is delivered as several consecutive PDFs.
  • Unsupported image formats are skipped and listed in the report.
  • Archive metadata such as ComicInfo.xml is not added as a PDF page.
  • Extremely large pages are scaled down to stay within the browser's pixel limit, and those pages are listed in the report.

CBR/CBZ to PDF or PDF to CBZ?

Use CBR/CBZ to PDF when you want a fixed-layout document for printing, sharing, or general PDF readers. A PDF to CBZ workflow is the opposite job: packaging PDF pages as an image-based comic archive for a comic reader.

Frequently Asked Questions

Can I convert both CBR and CBZ files to PDF?

Yes. This tool supports both common comic book archive formats. CBR usually uses RAR compression, while CBZ usually uses ZIP compression. The container is detected from the file header, so renamed files are still handled correctly.

What is the difference between CBR and CBZ?

Both formats normally contain an ordered sequence of comic page images. CBR uses a RAR-based container, while CBZ uses a ZIP-based container. Neither is a special image format — they are archives that hold ordinary JPG, PNG, WebP, BMP, GIF, or TIFF pages.

Will the comic page order be preserved?

Pages are sorted with natural numeric ordering, so filenames such as page1, page2, and page10 appear in the expected order. The preview shows exactly that order before you convert. If your archive uses unusual filenames, folders, or duplicate numbers, check the preview first.

Will the original image proportions be preserved?

Fit-to-image output keeps each page's original aspect ratio without stretching or unwanted cropping. A4 and Letter layouts are better for printing, but they may add margins around pages that do not match the paper ratio.

Can I convert manga with right-to-left reading order?

Yes. Choose Right to left (manga). This reverses the page order in the PDF itself, so the manga reads correctly from the first page in any PDF viewer — it does not change the image content.

Can I convert a password-protected CBR or CBZ file?

No. Standard, non-encrypted archives are supported. Password-protected, split, or multi-volume archives are reported before conversion and are not processed — extract or join them first.

Can I convert a very large comic archive?

Yes. Large archives need significant memory, so the tool adapts instead of refusing: pages are scaled down to a readable long edge when the archive is too heavy, and if it still does not fit, the PDF is delivered as several consecutive files that you can download together. Nothing is silently dropped — skipped or rescaled pages are listed in the report, and an archive is only turned away when even the scaled-down version cannot be built (for example a multi-gigabyte scan dump).

Are my comic files uploaded?

No. The archive is read, decompressed, and converted locally in your browser. Nothing is uploaded to a server, and no filename or page content is recorded.
