It is amongst the easiest to use, simple ePUB reader for free that is available for Windows operating system. The ePUB files have a default setting when opened in the reader. The background color is set as light yellow, which is easy on the eyes and suitable for long reading sessions. Background color can be changed from the advanced settings which is in a text document titled SumatraPDF-Settings.

What I liked about it
– Clutter-free, easy to use UI. It does the job pretty well without the unwanted frills.
– Small installation file size. 32-bit and 64-bit installers are under the size of 5 MB.
– A portable version is also available, which can be carried around with you on different computers on a USB-stick.

What could be better

2. Calibre

Calibre is an all-rounder in the document viewing segment. Besides being an exceptional ePUB reader, it is a full-fledged ebook management tool.


Kindle readers, including myself, use this application for fixing the formatting of ebooks and sending them to the device. Calibre has three modes, which are as a viewer/reader for ebooks, document editor, and the full-fledged ebook manager.

What I liked about it
– Fix the metadata of the ebook. You can either manually enter the correct information or search from the Internet, select the best metadata, and apply changes.
– Look-up the meaning of a word online/offline. There is a keyboard shortcut to look-up the meaning online as well. For setting up an offline dictionary sans Internet, the offline dictionary server needs to be setup. A guide to setup an offline Wiktionary can be found here.
– There is an option to utilize User CSS stylesheet to provide a complete overhaul of reading experience using a custom theme reading. If you know a little bit of HTML and CSS, then this feature would come in handy. It reduces the need for going through PREFERENCES for fine-tuning the view.
– Custom-themes are also available for enhancing your reading experience. They can be made by customizing your settings to you liking and saving it from the THEMING section of the PREFERENCES.

What could be improved
– Some ePUB ebook’s text is not correctly displayed. Wild characters appear instead of the text.

FBreader is another open-source free ePUB reader for windows 10 that can cater to different formats of the ebook, which includes the likes of ePUB and ePUB 3.


Other support formats are Mobi, FB2, PDF, Plucker, CHM. On the first launch, users will be prompted to set a path directory for opening and storing books. Margins, line spacing, and fonts, amongst other things, can be set from the Settings menu.

What I liked
– The progress bar can be customized according to reader preference.
– Online network libraries such as Manybooks, Feedbooks, Shucan catalog, etc. can be used to access books for free and a fee.
– Custom keyboard shortcuts can be set for over a dozen predefined actions. There is an option to set a delay for keys pressed as well to avoid any accidental call-to-action.
– Android and iOS versions of the reader available so that you can take your favorite ePUB reader to the smartphone.

What could be improved
– Drag and drop to open feature is not available in this reader. Manually browsing the ebook works fine, but a drag and drop option is not too much to ask, in my opinion.

4. Adobe Digital Editions

– Intuitive pop-up notes can be added anywhere in an ebook by highlighting the text.

What could be improved
– There is a general lack of customization for augmenting the reading experience.
– Dictionary is somewhat missed by many. A more natural alternative to be added would be have been a selection search feature that searched for the meaning of a word online, like some of the ebook readers mentioned offers.

5. Bookviser

Bookviser is an ebook reader that provides the feeling of reading an actual book instead of a conventional reading setup.

9. Kobo eBooks

Kobo is an epub reading app by Rakuten, is an ebook reading app with an integrated store for purchasing books from the app itself.
