CBZ to PDF - Free Online Browser Tool

Convert comic book archives (CBZ) into single PDF documents, in page order.

A CBZ is a ZIP full of numbered page images, which a browser can open without help. A CBR is the same idea built on RAR, and no browser can unpack that, so the page names the one it accepts.

This cbz to pdf utility runs completely inside your web browser. Your document is opened locally and processed on your own device using JavaScript and WebAssembly, so your file is never uploaded to any server. There is no signup, no watermark and no limit on how many documents you can handle.

  • 100% client-side - files never leave your device
  • Instant processing, no upload wait
  • Works on desktop, tablet and mobile
  • Free forever, no account required

How to Use the CBZ to PDF Tool

Four steps, and the whole thing runs locally on your own device.

  1. Add the archive

    Choose a .cbz file. A .cbr is detected and reported, because its RAR compression cannot be opened here.

  2. Choose how pages are fitted

    Full-page fitting uses every pixel for artwork, while A4 suits a printed stack.

  3. Sort the pages naturally

    Names are compared as numbers as well as text, so page 10 follows page 9 rather than page 1.

  4. Save the collected issue

    Each image becomes its own page in a single PDF, ready for any reader that opens PDFs.

Frequently Asked Questions

How is the page order decided?

By the file names inside the archive, compared with numbers treated as numbers, so a zero-padded or unpadded numbering scheme both come out in reading order.

Are double-page spreads kept together?

A wide image is fitted across a wide page, so a spread stays whole rather than being split down the middle or squashed upright.

Is the artwork re-compressed during the conversion?

Each page is decoded and re-encoded as a JPEG at high quality, so it is visually faithful but not a byte-for-byte copy of the original.

What can I do with a CBR file instead?

Unpack it with a RAR tool and re-pack the images as a ZIP, then rename the copy to .cbz and bring it back here.

Is there a size limit on the archive?

None is imposed by this page. A very large archive is limited only by the memory your browser and machine have available.
