Which files can I read?

Koofy Reader supports TXT and DRM-free EPUB files, including images embedded in EPUB books. It is not a PDF viewer or a library ebook lending service.

Make reading comfortable

Adjust fonts, text size and line spacing, add bookmarks and continue reading. The app offers Korean, English and Japanese interfaces, with reading layouts for phones and tablets.

How does reading aloud work?

Text-to-speech uses your device’s speech engine and installed voices. Available languages and voice quality depend on your device settings. The guide below explains how to import your own files.
