The Complete Guide to EPUB: Create, Convert, and Read E-Books

Everything you need to know about the EPUB e-book format — how it works, how to create and convert EPUBs, and the best reading apps.

EPUB (Electronic Publication) is the most widely supported open e-book format. Unlike PDF, which has fixed page layouts, EPUB content reflows to fit any screen size — from phones to tablets to e-readers.

An EPUB file is essentially a ZIP archive containing XHTML content files, CSS stylesheets, images, and metadata. This open structure makes it easy to create and modify e-books with standard web technologies.

Creating an EPUB is straightforward: write your content in XHTML or Markdown, structure it with a table of contents, add metadata (title, author, publisher), and package it with ConvertCraft's EPUB tools.

Converting between EPUB and other formats is common. EPUB to PDF is popular for printing, while PDF to EPUB enables reflowable reading on mobile devices. ConvertCraft handles both directions in your browser.

For reading EPUBs, Apple Books (iOS/Mac), Google Play Books (Android/Web), Calibre (desktop), and Kobo devices all provide excellent support. Amazon Kindle uses its own format (AZW/KFX) but can import EPUBs through Send to Kindle.
