In the context of children's books, a digital file refers to any electronic version of a manuscript, illustration, or design that is used in the publishing process. These files can come in various formats, such as PDF, EPUB, or image files (like JPG and PNG), and they are essential for both eBooks and print production. Digital files allow authors, illustrators, and publishers to collaborate efficiently, make revisions easily, and distribute works to readers across multiple platforms. This technology has transformed how children's literature is created, shared, and enjoyed.
