CBR is a comic archive built on the RAR format - the pages sit as individual image files inside the archive, usually JPEG or PNG. Practical for a comic reader, but awkward as soon as you need the pages elsewhere: to print, to read without a special app, or to archive in a universal format. This tool reads your CBR completely and places each page as its own page in a PDF.
The unpacking runs through a real, in-browser RAR read engine (libarchive, BSD-licensed - no proprietary unrar needed) that understands RAR 4 and RAR 5 alike. Pages are sorted into natural filename order before being embedded into the PDF - this matters because some archives store their entries internally in a different order than the filenames suggest. Each image page is embedded full-bleed: the PDF page takes the exact pixel dimensions of the image.
Everything runs entirely locally in your browser - no upload, usable offline too. Honestly framed: PNG and JPEG pages are embedded, by far the most common in comic archives; other image formats and metadata files like ComicInfo.xml are skipped. If an archive holds no embeddable image page, or is password-protected or damaged, the conversion stops with a clear message rather than producing an empty PDF.

Limitations: Reads a CBR (RAR archive, version 4 and 5) and converts it 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 and metadata files are skipped. Password-protected CBR files are clearly rejected as "password-protected". A genuinely damaged archive, or one with no embeddable image page at all, is likewise clearly rejected.
No. The unpacking and PDF build happen entirely locally in the browser - even offline.
Yes. Pages are sorted numerically by filename before embedding, independent of how the archive stores them internally.
No. The original images are embedded unchanged, not re-compressed.
It is clearly detected and rejected as password-protected, instead of being mishandled.
