Epub.js is a JavaScript library for rendering ePub documents in the browser across many devices. It provides interfaces for common ebook functions such as rendering, persistence, and pagination without requiring a dedicated application or plugin.
Use cases
- render epub books in a web browser
- build an online ebook reader
- display paginated epub content in a web app
- embed epub reading into a website
- create a continuous scrolling epub reader
- read epub files on mobile and desktop browsers
When to choose
- you need to render EPUB files client-side in the browser
- you want paginated or continuous scrolling ebook display without building a native app
- you need a permissively licensed (FreeBSD) epub rendering library
When to avoid
- you need to convert EPUB to other formats like PDF or Mobi
- you need server-side epub processing rather than browser rendering
- you need a full-featured native ebook application
