About
EPUB Online Viewer is a free web application that lets you read EPUB ebooks directly in your browser. We built it for people who want a simple, private way to read ebooks online—without installing apps or creating accounts.
Our goal
We want reading EPUBs to be as easy as opening a website. You upload a book, it’s saved in your browser on your device, and you read it in a clean, full-screen reader with table of contents, font and theme options, and automatic position saving. We don’t store your books on our servers and we don’t require an account. Your reading stays on your device and under your control.
How it works
When you upload an .epub file, the app processes it in your browser and stores it locally. When you open a book, the reader loads the content from that local storage and displays it. All of this happens on your device; we don’t receive or host your book files. The app supports standard EPUB 2 and EPUB 3 and works on desktop and mobile browsers.
Who we built it for
We built EPUB Online Viewer for anyone who reads ebooks: students with course materials, travelers with a few books on their device, book lovers building a digital library, or anyone who wants a simple, private way to read EPUBs in the browser. No app store, no account, no subscription—just open the site, upload a book, and read.
What we care about
We care about privacy: your books stay on your device and we don’t store or read them. We care about simplicity: no sign-up, no installation, no learning curve. We care about openness: EPUB is an open standard, and our app works in any modern browser. We want reading online to feel as good as reading on a dedicated e-reader.
