- Description
- An RTF file is a common text file format that supports "rich text." It includes several types of text formatting, such as bold type, italics, different fonts and font sizes, and custom tab settings. RTF files also support objects and images, such as .JPG and .PNG files, saved within the text file.
- A KEPUB file is an EPUB ebook with extra Kobo markup (koboSpan elements and a kobo.js script) that Kobo e-readers use for their faster renderer, page statistics and highlighting. It is usually saved as .kepub.epub; any EPUB reader can open it.
