Why convert OPF to ICO?
An OPF file is the package document inside every EPUB ebook, describing the book's metadata and listing the files it contains. The image shows the book title as a heading, a table of its creator, language and identifier, and a numbered list of the files in the package manifest.
ICO output is a 256 × 256 pixel Windows icon: the image is scaled to fit with its proportions kept, and the surrounding space is transparent.
