Free eBook Reader Apps Supporting EPUB, PDF, and MOBI
Books aren’t limited to Kindle shelves anymore. If you read PDFs for work, EPUB novels at night, or comics on weekends, a free eBook reader app can handle it all without forcing a subscription. Here’s the same-style intro content written specifically for free eBook reader apps.
🔍 Finding the Right Free eBook Reader App: Where Do You Start?
Not all free eBook reader apps are built for the same purpose. Some are designed for PDF documents, others are better for EPUB novels, and a few support everything from MOBI to comics (CBZ/CBR).

🔍 Search, Highlights & Bookmarks
- Search text within a book or document
- Add bookmarks to return later

- Save notes or quotes (availability varies by app)
📲 Offline Reading & Performance
