About the reader

Books belong with their readers.

Online EPUB Reader is a free browser-based reading tool built around a simple promise: opening a book should not require uploading it, creating an account or installing an app.

Why we built it

Reading an EPUB file should be as straightforward as opening a webpage. We designed this reader to remove the usual detours—software downloads, signup forms and remote file processing—so you can get to the book quickly.

Private by design

Compatible books are processed on your device by your browser. The reader does not send their contents to our servers. Books, progress and reading tools can be stored locally in your browser when you choose to keep them, which means you stay in control of that data.

Useful without being noisy

Our aim is a calm, accessible reading experience with practical controls for navigation, appearance and returning to your place. We favor features that make reading easier and keep the interface out of the way.

Built for the open web

Online EPUB Reader works in a modern browser and can keep its application files available for offline use after an initial visit. We focus on openly readable, DRM-free files. Retailer-protected books still need the retailer's authorized application.
