Convert EPUB to ICO

The EPUB (Electronic Publication) file extension is a widely utilized format for digital books and publications, leveraging its versatility across various e-readers and devices. Officially established by the International Digital Publishing Forum (IDPF) in 2007, it superseded the Open eBook standard. EPUB's structure allows for reflowable content, meaning text can adapt to different screen sizes, enhancing readability. It supports multimedia elements, such as images, videos, and interactive features, making it suitable for diverse digital publications beyond conventional eBooks. EPUB's adoption stems from its open standard, promoting broad compatibility and ease of access in the digital publishing landscape.

The ICO file extension, standing for "Icon", is integral to Microsoft Windows for storing icons of different sizes and color depths. Its primary use is to display graphical representations of executable programs, files, and folders within the Windows operating system. The ICO format's origins trace back to the early versions of Windows, evolving over the decades to support enhanced resolutions and alpha transparency. Today, ICO files ensure visually consistent and scalable icons that maintain their appearance across various display settings, aligning with modern user interface standards.
