About EPUB Reader

EPUB Reader is used to read EPUB ebooks in a web browser without installing an app such as Apple Books, Calibre or Adobe Digital Editions. Drop an EPUB 2 or EPUB 3 file to read it chapter by chapter with the book's own styles and images, jump around with the table of contents, change the text size, theme and font, and save a plain text copy. The file is opened on your device and never uploaded.

Key Features

Shows each chapter with the publisher's CSS, images and embedded fonts, including obfuscated fonts, with scripts switched off and remote images blocked
Light, sepia and dark themes, text size from 70% to 200%, a serif or sans serif override and adjustable line spacing

Why won't an EPUB I bought open in a browser reader?

Most store-bought EPUBs are locked with DRM: Adobe encryption for Google Play Books, Kobo and many library loans, Readium LCP for some libraries, and Apple FairPlay for Apple Books. The chapters are encrypted, so only the store's own app or Adobe Digital Editions can show them, and this reader tells you when it finds those markers instead of showing garbage. Kindle books are not EPUB at all; they use Amazon's AZW3 and KFX formats. DRM-free EPUBs from Project Gutenberg, Standard Ebooks, Humble Bundle and most technical publishers open normally.
