Folio: Offline Ebook Reader

Folio is a private offline reader built around the books and documents you own. Read EPUB, PDF, TXT and CBZ files in one calm personal library. Highlight passages, save notes, search your books, listen with read aloud, manage audiobooks and keep your reading progress available without depending on a required account or constant internet connection. READ YOUR OWN LIBRARY Import your files and keep them together in one reading space. • EPUB ebook reader • PDF reader • TXT document reader • CBZ comic reader • Local audiobook playback • Multiple-file import • Reading progress and resume position • Chapters and table-of-contents navigation Your library stays organized around your files instead of a locked content ecosystem. READ THE WAY YOU WANT Adjust the reading experience for long sessions, study or accessibility. • Font size and reading typography • Line, letter and paragraph spacing • Adjustable margins • Paginated or scrolling reading • Reading themes • Focus and Zen reading modes • Dyslexia-friendly reading options • Reading-time and progress tools Folio is designed to keep the book in focus rather than surrounding it with unnecessary interface. HIGHLIGHT, ANNOTATE AND REMEMBER Turn reading into something you can return to. • Highlights • Bookmarks • Passage notes • Notes and highlights hub • Vocabulary saving • Dictionary support • Search inside books • Jump back to saved passages Students, researchers and serious readers can keep useful ideas close to the source they came from. SEARCH YOUR LIBRARY Find information without remembering exactly where you read it. Folio can search across supported book content and library information including titles, authors, tags, notes and annotations. Search filters help narrow larger personal libraries so useful passages remain retrievable later. LISTEN WHEN YOU DO NOT WANT TO READ Use Android read aloud for supported text content or play local audiobook files directly inside Folio. Read aloud includes voice selection and speech controls. The audiobook player supports playback-speed adjustment, progress saving and sleep timers. Downloaded Android voices may also work offline depending on your device. BUILT FOR OFFLINE READING Folio is designed around local reading. There is no required account for your personal library. Your books, notes and reading progress remain on your device unless you choose to export or move them. Local backup and restore tools help you keep a portable copy of your library data. ORGANIZE MORE THAN BOOKS Create a reading system around your library. Use collections, notebooks, tags, favorites, series information, vocabulary and reading statistics to keep larger libraries manageable. Folio Pro expands this further with connected notes, backlinks, unified search, knowledge relationships, speed reading and additional library tools. DISCOVER PUBLIC-DOMAIN READING Browse supported public-domain sources including Project Gutenberg, Open Library and LibriVox where available. Download what interests you, then continue reading or listening from your own library. A CALMER PERSONAL LIBRARY Folio is for readers who want their files, notes and progress to remain useful long after a reading session ends. Import a book. Open the page. Keep reading.
