About this epub viewer
The EPUB viewer opens an ebook file and lets you read it in the browser without installing a dedicated reader app. Reader view renders each chapter with the book's own styles, fonts, and images, while a plain-text view extracts just the words for copying or download. Pick a chapter from the list and switch modes as you like.
It also suits a quick look at a book's structure — checking how chapters are split, confirming the title and author, or reading a section before extracting the full text. Chapter names come from the book's table of contents, and chapter text is decoded using each file's declared or detected character encoding, including legacy East Asian encodings such as EUC-KR, so accented and non-Latin characters read correctly.
Common uses
- Read a book chapter by chapter with its own styles and fonts in Reader view.

- Use Reader view to see the book with its own fonts and styling
