Thankfully, you have a wealth of ebook readers available that make it easier than ever to enjoy your favorite titles on various devices—from mobile to desktop to the web. Below, we’ll explore some of the best ebook readers, highlighting their features, advantages, and supported formats.
1. Amazon Kindle
Available on: Windows, macOS, Android, iOS, Kindle, Web
The official Kindle ebook reader app is a significant extension of Amazon’s popular Kindle hardware. This app allows you to seamlessly read Kindle books across multiple platforms. One notable feature is the ability to access your notes, view your library, and continue reading where you left off, regardless of the device you’re using. It’s also the home of the Kindle Unlimited subscription service.
Notably, the Kindle app supports more than just Kindle content; you can read PDFs, Word documents, RTF files, and even EPUB books, provided they’re not DRM protected. Amazon’s free Send to Kindle service allows you to send files easily to your Kindle app or device, making it a versatile option.

2. Calibre Ebook Reader
Available on: Windows, macOS, Linux, Android, iOS
Calibre is renowned not only as a reader but also as a comprehensive ebook management tool. It’s a cross-platform application that allows you to organize your library, and the portability feature lets you use it even from a USB drive.
One of Calibre’s standout features is its ability to automatically pull in ebook metadata, which can significantly streamline your search and organization process. While it does have a bit of a learning curve during setup, its ability to convert ebook file types for various devices is invaluable, making it an excellent tool for users who work between different platforms.

3. Sumatra
Available on: Windows
Sumatra is a free and lightweight ebook reader for Windows, making it an excellent option for those looking for a quick and efficient reading experience. It may not offer cross-platform compatibility, but it supports multiple formats including EPUB, PDF, MOBI, and more.
While its interface is minimalistic—lacking advanced features like bookmarks or annotations—Sumatra excels in delivering a straightforward reading experience. If you only need an app to open and read ebooks without any frills, Sumatra is a strong contender.

4. Favourite Book Reader (FBReader)
Available on: Windows, macOS, Linux, ChromeOS, Android, iOS
FBReader is a gem in the world of ebook readers. Although it was initially open-source, it still supports cross-platform reading across many devices. This reader is compatible with several formats, including EPUB, MOBI, and RTF.
The app offers a convenient cloud reader option that syncs your books and reading progress across devices via Google Drive. Navigation is smooth and user-friendly, providing an overall pleasant reading experience.

5. OverDrive/Libby
Available on: iOS, Android, Web
OverDrive partners with local libraries to offer free access to a broad range of ebooks, audiobooks, and videos. The Libby app serves as the primary reading interface, combining a sleek design with features like bookmarks and adjustable font sizes.
Libby even allows you to send books directly to a Kindle device in the U.S., provided your library participates in this feature. However, it’s essential to note that Libby doesn’t support uploading personal ebooks, focusing solely on library access.

6. Kobo Reading App
Available on: iOS, Android, Web
Kobo serves as a rival to Kindle, boasting its bookstore and subscription plans. The Kobo reading app provides essential features like font options, a built-in dictionary, and a day/night mode.
However, one thing to keep in mind is that importing non-Kobo content, such as PDFs or EPUBs, can be limited. If you primarily read books from the Kobo store, this app will serve you well.

7. Nook App
Available on: iOS, Android, Web
The Barnes & Noble Nook app shares several similarities with the Kindle app, allowing you to customize font options, add bookmarks, and search through your library.
What’s helpful is that, although Barnes & Noble encourages users to purchase ebooks through their platform, you can upload various formats, including PDFs and EPUBs, as long as they aren’t DRM protected. Just keep in mind that browsing files on your phone through the Nook app may be somewhat limited.

8. Adobe Digital Editions
Available on: Windows, macOS, Android, iOS
Adobe Digital Editions stands out in an era dominated by DRM restrictions. This app is highly recommended by many ebook stores for verifying purchases. It supports multiple formats and allows you to read a mixture of content from various sources, making it a fantastic choice if you have ebooks from different stores.
Its features include bookmarks and customizable font sizes, ensuring a pleasant reading experience across devices.

9. Scribd & Everand
Available on: Android, iOS, Web
Scribd and Everand function as part of a subscription service, providing users access to a significant library of ebooks, audiobooks, and documents. While you can upload your text files to Scribd, they must be copyright-free.
Both apps allow for a feature-rich reading experience, enabling users to adjust text, brightness, themes, and more. You can also take notes and bookmarks, enhancing your reading comprehension and enjoyment.

10. ReadEra
Available on: Android, iOS
For those with various ebook formats, ReadEra is an excellent choice. While it doesn’t offer a bookstore, it excels at importing and managing existing content. Supported formats include EPUB, PDF, and MOBI.
Though customization options for fonts and backgrounds are limited, ReadEra provides functionalities for bookmarks and organizing your library efficiently.
