An EPUB Reader for Chrome that keeps your books on your machine

Open a DRM-free EPUB in one tab and read it. Online EPUB Reader is free, has no ads, and there is no account to make.

.epub

Your books never leave your device

There is no account, because we did not build one. Nothing to sign up for, nothing to collect, nothing sent anywhere. Your books sit in local storage on your computer, and once the extension is installed you can read with the wifi off.

With most tools you cannot tell where your file goes after you hand it over. Here there is nowhere for it to go.

Page 59 is still page 59 tomorrow

The top-rated reader on this shelf told its users flat out that page numbers are not feasible in EPUB, because the format is not standardized.

Here a page is a fixed portion of text. Bump the font up two sizes, drag the window narrow, open the same book on a different screen: page 59 holds. You close the laptop knowing where you stopped, and the number is still there in the morning.

  • Works offline

    Free to use, nothing sold to you.

  • No account

    Nothing to sign up for, nothing collected.

  • Built for calm

    Warm and dark themes, adjustable type, no distractions.

A library, not a folder of files

Your books show up as covers, with progress on each one, so you can see at a glance which three you left half-read. Star the ones you return to. Sort by title or by how far along you are. Deleted a book by accident? Trash holds it for 30 days.

Reading tuned to your eyes

It is late, the room is dark, and the screen is a cold white slab. Turn the warmth up and the brightness down, or switch to one of the four dark themes: Dust, Graphite, Night, Midnight. In daylight there are four more: Paper, Sepia, Notebook, Mint. Set the type to whichever of the six faces sits easiest with you, Literata and Atkinson Hyperlegible included, then set line spacing, column width and justify, and read in pages, in a two page spread, or scrolling.

A library that comes with the reader

A shelf of public domain classics is built into the extension. Open the library, pick a book, and you are reading a minute after install, before you add a single file of your own.

Questions

How do I open an EPUB file in Chrome?

Install the extension, click its icon, and drop your .epub file onto the library. No converter step, nothing uploaded. Click an .epub link on the web and it lands in the reader too, downloaded to you. If the book sits in your Drive, open it from there.

Does it work offline?

Online EPUB Reader works with no connection once it is installed. Your library, your books and your place in them are all there on planes, on trains, on a dead hotel wifi. The books are already on your machine, so there is nothing to fetch.

Is it free?

Online EPUB Reader is free. No ads, no locked chapters, no trial that runs out.

Does it upload my books to the cloud?

The reader keeps your books in local storage on your own computer and never sends them anywhere. There is no server holding your library, no account tied to it, nothing syncing in the background.

What formats does it read?

DRM-free EPUB. That is the honest answer: no PDF, no MOBI, no other formats. Books protected by a store's DRM will not open here.

Does it work on Windows or a Chromebook?

Yes, anywhere Chrome runs: Windows, Mac, ChromeOS. It is useful on a locked-down work computer or a school Chromebook where you cannot install a program, since a Chrome extension is all you need.

Why do page numbers stay the same when I change the font?

Because a page here is a fixed portion of text rather than whatever happens to fit on the screen, so resizing the window or the type changes how it looks, not what page you are on.

Where do the built-in classics come from?

Public domain texts in CC0 editions, six titles we chose deliberately rather than a random shelf of free files.
