Lately, the demand for digital books has increased as people find it more comfortable to reading a book on their handheld devices, Kindle or PC. When it comes to Linux users, there are various ebook apps that will serve your purpose in reading and organizing your collections.

In this article, I have compiled some of the best ebook readers for Linux. These ebook readers are best suited for PDFs, epubs, and other e-book formats.

1. Calibre

Calibre is one of the most popular eBook apps for Linux. To be honest, it’s a lot more than just a simple eBook reader. It’s a complete eBook solution. You can even create professional eBooks with Calibre or even remove DRM from Kindle books.

With a powerful eBook manager and easy-to-use interface, it features the creation and editing of an eBook. Calibre supports various formats and syncing with other eBook readers. It also lets you convert one eBook format to another with ease.

The biggest drawback of Calibre is that it can be heavy on system resources, and that makes it a difficult choice as a standalone eBook reader. Of course, that depends on what kind of system you’re rocking.



  • Calibre allows sorting and grouping eBooks by managing the metadata. You can download the metadata for an eBook from various sources, or create and edit the existing field.
  • Calibre supports all major eBook formats and is compatible with various e-readers.
  • You can convert any ebook format to another one with the option of changing the book style, creating a table of content, or improving margins while converting. You can also convert your personal documents to an ebook.
  • Calibre can deliver stories from various news sources or through the RSS feed.
  • It gives an option of hosting your eBook collection on its server, which you can share with your friends or access from anywhere, using any device. The backup and import/export features allow you to keep your collection safe and easy portability.
  • Available cross-platform (Linux, Android, iOS, Windows, and macOS)


You can find it in the software repository of all major Linux distributions. For Ubuntu, search for it in the Software Center or use the command below:

sudo apt install calibre

This will install a dated version of the app. So, if you want to install the latest version of Calibre, you can use the binary install method using the following command:

sudo -v && wget -nv -O- https://download.calibre-ebook.com/linux-installer.sh | sudo sh /dev/stdin

If you encounter an untrusted certificate error, you can use the command below to install it successfully:

sudo -v && wget --no-check-certificate -nv -O- https://download.calibre-ebook.com/linux-installer.sh | sudo sh /dev/stdin

2. FBReader (Not FOSS anymore)

FBReader is a free, lightweight, multi-platform ebook reader, that is not open-source. It supports various formats like epubfb2mobiRTFHTML, etc. It also includes access to popular network libraries from where you can download ebooks for free or buy one.

FBReader is highly customizable with options to choose colors, fonts, page-turning animations, bookmarks, and dictionaries.

Ubuntu users can install it by typing the below command in the Terminal:

4. Lucidor

Lucidor is a handy e-book reader supporting epub file formats and catalogs in OPDS formats. It also features organizing the collection of e-books in local bookcases, searching and downloading from the internet, and converting web feeds and web pages into e-books.

Lucidor is a XULRunner application, giving you a classic look of Firefox with a tabbed layout that behaves like it while storing data and configurations. It’s the simplest ebook reader on the list and includes configurations like text justifications and scrolling options.


You can also look up the meaning of a word from Wiktionary.org by selecting a word and right-click > lookup word options. It also includes options for converting web feeds or web pages into e-books.


  • Firefox-like Interface.
  • Low storage footprint.
  • Not heavy on system resources.

As you can see above, the user interface is pretty straightforward to get used to, and new users should feel right at home when using Koodo Reader.


  • Intuitive User Interface.
  • Easy Library Management.

You can download an AppImage from the GitHub releases section. If you are unsure how to install it, then you can read our guide on how to use AppImage in Linux.

Alternatively, you can install it from the command line as well, using the flatpak package. If you don’t know how to do that, follow our resource on how to install Flatpak apps on Linux and type in the following commands:

flatpak install flathub io.github.troyeguo.koodo-reader
flatpak run io.github.troyeguo.koodo-reader

8. Foliate

Foliate is an eBook reader that is actively developed, which already provides the most essential features while also providing a great user experience.

It is an impressive alternative to the rest of the eBook readers mentioned above.



  • Ability to tweak the text.
  • Many pre-installed themes.
  • Support for bookmarks and annotations.


The most straightforward way you can install Foliate on your Linux system is by opting for either the Flatpak or the Snap version.

You can also head over to its GitHub release section to get the source code.

Final Words

Personally, I find Calibre best suited for my needs. Moreover, Bookworm looks promising to me and I use it often. Though, Foliate can be worth a try if you’re looking for something modern.

At the end of the day, choosing an eBook application totally depends on your preference and use cases.
