Windows users have always had plenty of options for opening EPUB files, but let's be honest: most of them look like they were built two decades ago. If you want to actually sit down and enjoy a book on your PC, you need an app that prioritizes clean design and distraction-free reading. Here are the 5 best EPUB readers for Windows in 2026.
1. Wizread (Best Overall & Best Design)
If you value a beautiful, modern user interface, Wizread is entirely in a league of its own. While other apps feel like database management tools, Wizread was built specifically to create a relaxing, book-like environment on your desktop.

Despite the name, SumatraPDF opens EPUBs as well. It is famous for being incredibly lightweight and fast.

- Cons: Extremely barebones; missing basic ebook features like robust library management and advanced formatting.
5. Freda
Freda is a popular app available in the Microsoft Store. It connects easily to Project Gutenberg and Smashwords to find free books.
