The best e-Pub reader for your platform?

Windows

Microsoft removed the built-in Edge EPUB reader in 2019. Windows has no native EPUB support — you need to install something.

Sumatra PDF is the right pick for most people: under 10MB, opens EPUB/PDF/MOBI/CBZ in under a second, no configuration required. No library view or sync, but if you just want to open a file and read it, nothing on Windows is faster. Portable version available for use on machines where you can't install software.

Mac

Apple Books is pre-installed and genuinely good. Double-click an EPUB in Finder — it opens, gets added to your library, and syncs to iPhone and iPad via iCloud automatically. Custom fonts, night mode, highlights, and bookmarks. Excellent EPUB 3 support. Use it as your default and only add other tools if you have specific gaps.

iPhone and iPad

Apple Books handles EPUBs well out of the box. Tap an EPUB attachment in Mail, tap a file in Files, or tap a download link in Safari — iOS offers to open it in Apple Books. Supports EPUB 2 and 3, offline access, iCloud library sync, reading progress sync across devices, and VoiceOver accessibility. The default for most users who don't have a specific reason to use something else.

Android

Android has no built-in EPUB reader — Google Play Books is pre-installed but requires uploading files through a browser rather than opening local files directly.

ReadEra for offline local reading — completely free, no ads, no account required, works directly from the file manager. Install it once and any EPUB you tap opens in ReadEra automatically. Supports EPUB, PDF, MOBI, FB2, and DjVu. Reading position saves locally. No cloud sync, but for local single-device reading it's the best zero-friction option.

Linux

Foliate for day-to-day reading. Clean GNOME-native interface, fast startup, annotations, bookmarks, and reading statistics. Available as a Flatpak (runs on any distro) or in most package managers. Handles EPUB 2 and 3, MOBI, and FB2. Good default for any GNOME or GTK-based desktop.

Any Browser (No Install)

Epublys' online EPUB reader works in Chrome, Firefox, Safari, and Edge on any OS. Drop in an EPUB or PDF, read immediately. Includes dark mode (Light/Dark/Sepia themes), font size controls, TOC sidebar, bookmarks, and full-text search for EPUBs. Files never leave your device — everything runs in the browser. Useful for:
