Start your book, freeThe EPUB file format for eBooks packages structured content and supporting resources in one file. A reflowable EPUB lets text adapt to the reading area; the EPUB standard also supports fixed-layout publications. Check the layout your EPUB uses instead of assuming the extension guarantees reflowable text.

Choose the EPUB file format when following text matters more than preserving one exact page design. An EPUB novel, narrative guide or course reader can adapt to the reading area when prepared as a reflowable publication. Review diagrams, comparisons and answer spaces before choosing the EPUB layout.
Think about what the reader needs to control. EPUB is a useful starting point for flowing text; PDF is useful when the arrangement of a page carries meaning. A workbook with an exercise beside its answer space may need a different design from a novel. You can prepare more than one edition when the reading tasks differ.
Prepare the EPUB file format for eBooks after resolving the manuscript decisions in Bookeen. Read the actual EPUB in the apps your audience will use. An EPUB review should cover navigation, chapter structure, images and different text sizes; a clean editor view alone is not a release check.
Plan the EPUB edition around its destination. File preparation and store publication are separate steps.

EPUB is used to distribute digital publications. For your book, the practical question is how readers will open and navigate it. Before sharing a release, try the file in the reading environment you plan to recommend and make sure its structure is easy to follow.
Neither choice fits every book. Start with the reading task: continuous text, a page-based reference, a printable worksheet or an illustrated spread. Compare the actual exports using a representative chapter. Choose the version that makes the material easier to use.
Prepare a dedicated print interior for a paperback. The printer needs a particular page size and layout, and you need to review the resulting pages as a physical book. Use the Print PDF guide below when you are ready to make those choices.
No. An export produces a file for you to inspect and distribute through your chosen channel. Publication, account setup and the destination’s review remain separate steps. Bookeen helps with preparing the work; you make the release decisions.
