Eluna Reader: Books, EPUB PDF

No subscription. No ads. No account. No AI. Eluna Reader opens almost any book or document — over 20 formats — and keeps every page, note and bookmark on your own device.

Most reading apps rent you your own library. Eluna never does: reading is free, the only purchase is a one-time tip that unlocks nothing, and anything you write stays yours.

READS 20+ FORMATS
EPUB (2 & 3), FB2, FB3, MOBI, AZW3, PRC, PDF, DjVu, DOC, DOCX, ODT, RTF, TXT, Markdown, HTML, CHM, UMD and comics (CBZ, CBR, CBT) — even books inside ZIP archives. One shelf for novels, manga, manhwa, textbooks and PDFs alike.

READ-ALOUD & REAL PAGE NUMBERS
Listen to any book with the built-in read-aloud voice, the current sentence highlighted as it speaks. See real page numbers — "page 128 of 512" — not just a percentage, in a status bar you assemble yourself.

TYPESET IT YOUR WAY
Paged mode with slide, fade and 3D page-turn animations, or a smooth continuous scroll. Portrait or landscape, two-page spread on a tablet. 5 bundled fonts including OpenDyslexic, or import your own TTF/OTF. Fractional font size, four independent margins, line and paragraph spacing, hyphenation. Keep the publisher's own CSS, or force your own styling on top.

NOTES THAT LEAVE THE APP
Highlight in many colors, tag notes with hashtags, pin and group them into a second brain. Export the whole library to Markdown, Obsidian, Readwise, JSON or CSV — and import it back. Your annotations belong to you, not to a database.

SYNC WITHOUT AN ACCOUNT
Reading position, highlights, notes and reading statistics stay in step across iPhone and iPad through your own iCloud — encrypted end to end, no server, no sign-up. Speak KOReader's sync protocol (KOSync) or point it at your own WebDAV folder to plug into Kavita, Komga or Calibre-Web.

FIND ANYTHING
Full-text search across every book, inside PDF pages, and through all of your notes at once. On-device OCR reads scanned PDFs so even they become searchable — nothing is ever uploaded.

BUILT FOR LONG READING
Automatic day and night, sepia, OLED-black and e-ink themes. Blue-light filter, on-screen reading ruler, brightness control and auto-scroll. Remap tap zones, swipes and the volume keys. Dictionary and translation on any word — strictly opt-in. Browse OPDS catalogs and your own servers.

PRIVATE BY DEFAULT
Works fully offline. No trackers, no telemetry, and no AI trained on your books. Optional Face ID / Touch ID lock and screenshot protection. Every connection the app can make is listed on a single screen.

61 LANGUAGES, 63 BADGES
The whole app is translated into 61 languages. Reading statistics, daily streaks and 63 achievement badges keep the habit going.

Eluna Reader — a power reader that respects your library and your privacy.
