Why convert CBZ to PDF?
CBZ is a ZIP archive of page images used by comic and manga readers. Each image inside is one page.
Every page in the archive is converted, in reading order.
PDF is the format forms, schools, employers and portals expect. One tidy document is also easier to send and print than a folder of images.
