A CBZ is essentially just a ZIP archive whose entries hold the individual comic or manga pages as image files - usually JPEG or PNG, named in reading order. The format is perfect for dedicated comic readers, but awkward as soon as you need the pages elsewhere: to print, to read on a tablet without a reader app, to send to someone, or simply to archive in a universal format. This tool unpacks the archive and places each page as its own page in a PDF.
The pages are sorted in natural filename order, so page 2 correctly comes before page 10 - exactly the order a comic reader would show. Each image page is embedded full-bleed: the PDF page takes the exact pixel dimensions of the image, nothing is cropped, stretched or given a white border. Helper files some archives carry along (such as ComicInfo.xml or hidden system files) are skipped. The result is a single PDF with exactly as many pages as the archive held image pages.
Everything runs entirely locally in your browser (fflate to unpack, pdf-lib to build the PDF, pure JavaScript - no upload, even offline). Honestly framed: PNG and JPEG pages are embedded, by far the most common in CBZ archives; rare pages in other formats (such as WebP) cannot be embedded directly and are skipped. If an archive holds no embeddable image page at all, the conversion stops with a clear message rather than producing an empty or misleading PDF.

Limitations: Converts a CBZ (a ZIP of page images) to a PDF: one image per PDF page, in natural filename order, full-bleed at the original pixel size. PNG and JPEG pages are embedded; other image formats are skipped. Helper and system files in the archive are ignored. CBZ has no text layer - there is no formatting or table structure in the document sense, each page stays a single raster image. A corrupt archive, or one with no embeddable image page at all, is rejected with a clear error. CBR (RAR-based) is not supported.
No. The unpacking and PDF build happen entirely locally in the browser - even offline.
Yes. Pages are sorted numerically by filename, so e.g. page 2 appears before page 10 - the usual reading order.
No. The original images are embedded unchanged, not re-compressed; the PDF page takes the image pixel dimensions.
No. CBR is a RAR archive for which there is no freely licensed decoder. CBZ (ZIP) is supported.
