EPUBtiedosto

EPUBtiedosto is a file format used for digital books and publications. EPUB stands for Electronic Publication and is an open standard developed by the International Digital Publishing Forum (IDPF). Its primary purpose is to provide a standardized, reflowable format for e-books, meaning the text can adapt to different screen sizes and devices. This contrasts with fixed-layout formats, which maintain a set page structure.

The EPUB format is based on web technologies, including XHTML, CSS, and JavaScript. This allows for rich content, such as interactive elements, embedded fonts, and adjustable text formatting. EPUB files are essentially compressed archives, typically containing HTML or XHTML files for content, CSS for styling, images, and metadata. This structure makes EPUB files flexible and accessible across a wide range of e-readers, tablets, smartphones, and computers.

One of the key advantages of EPUB is its open and royalty-free nature, which has contributed to its widespread adoption by publishers and readers. It supports features like digital rights management (DRM) for copyright protection, though not all EPUB files implement DRM. The reflowable nature of EPUB is particularly beneficial for reading on devices with varying screen dimensions, ensuring a comfortable reading experience without the need for constant zooming or scrolling.
