| Description | .epub (Electronic Publication) The .epub file format is a widely used and freely available eBook standard, designed by the International Digital Publishing Forum (IDPF). EPUB files are designed for reflowable content, meaning that the text display can be optimized for the particular display device used by the reader of the EPUB-formatted book. It allows for the embedding of fonts, images, and other media necessary for a full multimedia experience, and is compatible with many e-readers and reading apps. This format is popular for digital books because it's capable of adapting to different screen sizes and supports features like bookmarking, text highlighting, and note-taking. |
