What to check first

Start with the EPUB file

An EPUB file is a packaged ebook made from chapter files, metadata, styles, fonts, and navigation information. A viewer reads the package and shows the chapters so you can read or inspect the book without installing a full ebook app.

Chapter names come from the book's table of contents, so the chapter list reads correctly even when a book's in-page headings are styled or named unusually.

Reader view or plain text

The viewer offers two modes. Reader view renders each chapter the way the book intends — with its own styles, fonts, and images — so the page looks like it would in an ebook app. Plain text extracts just the words for copying, counting, or cleanup.

Pick a chapter from the list, read it, and move on when you are ready. Switch to plain text only when you need to copy or download the words.

  • Switch between Reader and Plain text
  • Browse chapters from the contents
  • Copy or download text in plain-text mode

Encodings and copy-protected books

Ebooks and text files are not always saved as UTF-8, so the viewer detects common encodings — including UTF-8, UTF-16, Windows-1252, and East Asian encodings such as EUC-KR — so accented and non-Latin characters read correctly.

A few commercial ebooks scramble the underlying text and restore it visually with an embedded font to prevent copying. Those books read correctly in Reader view, but their text cannot be extracted as plain text — that protection is doing exactly what the publisher designed it to do.

Frequently asked questions

What is an EPUB viewer?

An EPUB viewer opens an ebook package and shows its chapters. Reader view renders the chapter with the book's own styles and fonts, while plain text shows just the extracted words.

Why does some text look garbled in plain-text mode?

A few commercial ebooks deliberately scramble the underlying text and display it with an embedded font. Read those in Reader view; plain-text extraction cannot reverse that copy protection.
