📖 Meet EPUB Reader for Google Drive™ — the books you keep in Drive, opened in a browser tab. Right-click an epub file in Google Drive™, choose Open with, and the book opens on a quiet page that remembers where you stopped. No account to create, no converter to run, nothing uploaded to anybody.

🚀 How to read epub files from Google Drive™ in four steps:
1. Install this epub reader from Google Workspace™ Marketplace.
2. Right-click a book in Google Drive™ and choose Open with.
3. Pick EPUB Reader and press Open once.
4. Read. Your place is saved the moment you truly read.

🔟 Ten reasons readers open epub files here:
1️⃣ One right-click in Google Drive™ turns a stored file into a book
2️⃣ Page numbers that stay put when you change the font
3️⃣ A private library with covers, progress and favorites
4️⃣ Four light and four dark themes with warmth and brightness dials
5️⃣ Six typefaces plus line spacing, width and justify controls
6️⃣ Page, Spread and Scroll layouts on one switch
7️⃣ Search inside the book, and a table of contents one tap away
8️⃣ A lightbox for maps and pictures with zoom and rotate
9️⃣ Everything readable offline once the book has landed
🔟 Six classics on the shelf before you add a single file of your own

🔑 It sees one file — the one you opened
This epub viewer asks Google for the single book you picked in Open with. It never lists your Drive, never touches the file next to it, and never writes to the book it read. Press Open, approve the Google popup once, and that one book arrives.

📚 A library, not a download folder
The book you open from Google Drive™ is copied into a library that lives in this browser on this device. Covers, reading progress and favorites are yours to arrange, and the Trash keeps a removed book for 30 days in case you change your mind. Calibre is a fine desktop companion, but an epub reader online should not ask you to install anything at all: this is an online ebook reader that lives in a tab.

📌 Pages that stay put
A typical epub file reader renumbers the whole book every time you resize the window or change the text size. Here a page is a fixed portion of text, so page 59 is still page 59 tomorrow, on any screen. That is what makes an epub web reader feel like a printed book.

🧭 Built for long books
The table of contents marks where you are now. A thin progress line runs the full width of the screen with a small diamond for every chapter, and the header counts the minutes left in this chapter instead of a vague percent. Full screen hides everything but the words, and search finds a phrase across the whole book.

🎨 Reading, tuned to your eyes
An ebook viewer should look like a book. Pick Paper, Sepia, Notebook or Mint by day, or Dust, Graphite, Night and Midnight after dark: dark mode is built in, not bolted on. Six fonts ship with it, Literata and Atkinson Hyperlegible among them, plus warmth and brightness dials for late evenings.

📂 More than EPUB once you are here
EPUB is the format this app registers in Google Drive™. Drop a file onto the shelf and the same reader also opens Kindle-style MOBI and AZW3 books, or FB2 plain and zipped. A text file or a Markdown note opens as a book too, and a Word document keeps its headings, lists and pictures. PDF and comics are not supported yet.

🔒 Private by design
➤ no account here, nothing collected, no ads
➤ the book stays in local storage on your own machine
➤ the file in your Drive is read, never written to
➤ everything works offline once the book has landed

💡 You already have one — this page. Press Open once and you read epub Google Drive™ keeps for you, in the tab you are already in.

❓ How to view epub files on a Chromebook?
💡 The same way. It is a light epub reader Chromebook owners keep open in a tab, and it works on Windows and Mac as well.
