Windows 10: How to Open an EPUB File with Microsoft Edge or an EPUB Reader

We show you how to open an epub file in Windows 10 with the best compatible ebook reader apps,, in Microsoft Edge, and Google Chrome.


If you enjoy books, there's a good chance you've come across the EPUB format. As the official IDFP standard for electronic book publication, it's used by EPUB reader devices like Kobo and is also distributed to users via library services.

Unfortunately, some users run into issues when wondering how to open epub files on Windows 10. There's no dedicated Windows EPUB reader and historically relied on its browser, , to manage digital publishing formats. However, with the closure of its eBook store and the release of the new Chromium Edge, this is no longer an option.

Today, we're going to be showing you how to open EPUB files in Edge with a browser extension instead, as well as with Microsoft-recommended Store apps and other third-party solutions like Calibre reader. Here are the best EPUB reader apps for Windows 10. Let's get started:

How to Open EPUB File with Microsoft Store Apps

Though Microsoft no longer has a dedicated EPUB viewer, there are some apps it recommends via its Microsoft Store that do the job just fine. For the most part, these aren't as fully featured as the win64 alternatives, but they support automatic updates and are usually quick to use.

  1. Visit the “Reading room” store collection

    Microsoft's list of recommended EPUB readers is known as the reading room. At the time of writing, it features 21 apps which will all act as a Windows EPUB reader. Simply click the app and press the “Get” button.

  2. Read your ebook

The Best Ebook Reader Alternatives to Open EPUB Files

As Microsoft's recommended store apps tend to be a bit barebones, it's worth considering a third-party win64 app. In most cases, these offer more customization, intelligent features for easier viewing, and more. We've rounded up the best options for you below so you can find your favorite EPUB reader for Windows:

  1. Cool Reader

    Cool Reader is the closest you'll get to the speedy Microsoft Edge-like ebook experience without using the browser. It's an XML/CSS-based ebook reader with a fully customizable palette, text size and re-formatting, smooth scrolling, and more. It doesn't have the prettiest interface in the world, but its snappiness can make up for it.

  2. Adobe Digital Editions

    Adobe Digital Editions was one of the first readers to adopt the EPUB format. It's completely free and lets you manage as well as view your files via a digital library. Due to its proprietary DRM, you can also use Adobe Digital Editions to borrow EPUB and PDF files from various public libraries.

  3. Calibre reader

    Calibre is likely the best EPUB reader you'll find on Windows. Though its e-book viewer is relatively simple, the functionality its library provides is unmatched. You can use Calibre to import and read epub files like any other app, but you can also edit individual lines, email them to an e-reader, edit metadata and tags, backup your library, and much more. It also acts as an epubconverter, letting you change from .epub to various other formats to suit different devices.

    Its reader lets you bookmark, customize font size and layout, look up words, view table of contents, set a custom background image, and everything else you'd expect. It's all provided free of charge with no ads.

      1. KDE Okular Document Viewer

        KDE Okular is less an EPUB reader specifically and more of a universal document viewer. You can use it to open various different formats, from epub to PDF, PostScript, XPS, and more. Nevertheless, it supports annotations, tables of contents, bookmarking, and plenty of other features to make the EPUB reading experience pleasant.

  4. Extra: Polar documents managing app

    Polar is an excellent application geared toward managing extensive document libraries. You can use it to keep track of how far you are into each book, view annotations, tag, and highlight. This makes it particularly useful for students, especially as you can cloud sync your titles to the cloud to access them from anywhere. While its epub reading functionality is limited, it can be a good tool for general management.
