EPUB Reader FAQ

What is an EPUB file?

EPUB is a popular open ebook format built for digital reading. Unlike fixed-layout files, EPUB text can reflow based on your screen size and reading preferences, which makes it useful on phones, tablets, and desktop readers.

How do I read an EPUB file?

Use an EPUB reader or EPUB viewer, then open your .epub file and start reading chapter by chapter. In this app, choose Add New Book, load the file, and navigate with the chapter list and preview controls.

How do I open an EPUB file on PC or Windows?

You can read EPUB files directly in a modern browser with this web app, so you do not need heavy desktop software. This works well as an ebook reader for PC and as an EPUB reader for Windows.

What file types are supported?

EPUB is the primary format. PDF and TXT are also supported as optional formats, so you can keep different book sources in one free EPUB-focused reading tool.

Where are books and progress saved?

Data is saved locally in your browser storage (IndexedDB). Clearing site data removes saved content.

Can I move my library to another device?

Yes. Export your library to a backup .txt file and import it on another device.

Do I need an account?

No. EPUB Reader is designed to work without sign-up.
