Can you make an eBook in InDesign?
InDesign also has excellent capabilities for EPUB design, with options that will help you create both fixed-layout and reflowable eBooks (skip to Tip 3 below to find out more).
How do I create an EPUB in InDesign?
Do one of the following: Open the document and choose File > Export. Specify a filename and location. From the Save as Type list choose EPUB (Fixed Layout) or EPUB (Reflowable), and then click Save. In the EPUB Export Options dialog box, specify the desired options and click OK.
How do you layout a book in InDesign?
Book files are separate from document files. For example, when you choose the Save Book command, InDesign saves the changes to the book, not the documents in the book. To save an existing book under the same name, choose Save Book in the Book panel menu, or click the Save button at the bottom of the Book panel.
