Some comic-book readers accept CBR archives but not FB2 ebooks. Converting the book means rendering its pages as images and packaging those images in a RAR archive; the result is no longer reflowable ebook text.
What FB2 is
FB2 (FictionBook 2) is an XML-based ebook format used mainly for novels and other text-heavy books. It stores structured content such as chapters, headings, metadata, and images; reading apps determine how the text flows on screen. You may encounter FB2 files from ebook libraries or create them with editors such as FictionBook Editor. Calibre and many ebook-reading apps can open FB2.
What CBR is
CBR is a comic-book format: a RAR archive of page images, usually ordered by filename. Comic readers use it to display one image per page. It suits illustrated, fixed-page content, but it does not preserve an FB2 book’s reflowable text, searchable text, or chapter structure. A file renamed to .cbr is not necessarily valid; its contents must be a RAR archive.

Offline with desktop software
On Windows, macOS, or Linux, use the free Calibre ebook manager to render the FB2 as PDF, then Poppler’s pdftoppm utility to make page images. In Calibre, select the book and choose Convert books → Output format: PDF. Render the PDF in a terminal with pdftoppm -png -r 150 book.pdf page. Rename the images with zero-padded numbers, such as page-001.png and page-002.png, so comic readers display them in the right order.
To create the CBR archive, open the numbered images in WinRAR on Windows, choose Add to archive, select RAR as the archive format, and name the archive with a .cbr extension. Calibre and Poppler handle the conversion to images; WinRAR is needed for the RAR packaging step.
Quality and limitations
The PDF page size, margins, font size, and rendering resolution determine the appearance and file size of the CBR. Higher resolution preserves small lettering but produces larger images. Since each page is rasterized, text is not selectable or searchable in the CBR, and the page breaks are fixed rather than adapted to the reader’s screen.
