Furigana EPUB Export
Mekuru can export a copy of any EPUB in your library with furigana baked into the file, so you can read it with readings in any other EPUB reader — or share a furigana-free copy of a book that shipped with ruby text.

How to Export
- Long-press the book in the Library tab.
- Choose Export as EPUB.
- Pick how furigana should appear in the exported book:
- All kanji - generate furigana for every kanji word
- Kanji above JLPT level - generate furigana only for kanji above a JLPT level; an N5-N1 picker appears, preset to your reader's furigana level
- As published - keep the book's original ruby text unchanged
- None (remove existing) - strip all ruby text from the book
- Tap Export, wait for Preparing EPUB, then choose where to save the file.
The exported file is a standard EPUB — nothing about it requires Mekuru.
Notes
- The Kanji above JLPT level mode applies the same rule to furigana the publisher included: ruby stays only on kanji above your chosen level.
- Furigana generation uses Mekuru's built-in analyzer. If you see Furigana engine is unavailable, wait a moment after app launch and try again.
- Generated readings are more accurate with the Enhanced Furigana Dictionary installed.
- The original book in your library is never modified — export always writes a new file.
