What is a CBZ file?
Open a CBZ (ZIP) or CBR (RAR) comic archive and read its image pages without uploading it. Use Previous and Next, enter a page number, fit the page to the viewer or zoom, and download the current image. The .CBZ extension identifies a Comic Book Archive file, which is served with the application/vnd.comicbook+zip media type. You can open it here instantly — drop the file into the box above and it renders in your browser. Nothing is uploaded.
Image filenames are sorted naturally: page 2 comes before page 10, including pages stored in folders. Hidden archive metadata is ignored. Images are extracted as you navigate rather than loading the entire book into the viewer.
Besides this free online viewer, you can open Comic book (CBZ/CBR) files in desktop apps such as YACReader, CDisplayEx, Calibre — but here all you need is a web browser.
