Librera: EPUB & PDF Reader

Librera: EPUB & PDF Reader is a lightweight, feature-rich book reader that handles virtually every e-book format you'll encounter—EPUB, EPUB3, PDF, MOBI, DJVU, FB2, AZW, AZW3, HTML, ODT, XPS, CBZ, CBR, and more. At just under 14MB, it delivers a powerful all-in-one reading solution without the bloat.

Tailor your reading experience to perfection. Switch between night and daytime themes, adjust font sizes and styles, customize background and text colors, and apply textured backgrounds across all formats. Control reading direction for RTL languages, enable intelligent white space cropping, and use RSVP speed reading to read faster. Night mode protects your eyes, while configurable tap-zones and brightness adjustments let you read comfortably anywhere.

Your library, organized your way. Build a searchable collection with smart filtering by title, author, series, and genre. Sort books by author, size, or series, create favorites lists, and bookmark your progress across all supported formats. Open folders of images as books with automatic bookbinding, and search your entire collection in seconds.

PDF reading takes a powerful turn. Reflow text accurately, split pages for smaller screens, add notes and comments, select multi-line text with precision, and open password-protected documents. For comic readers, CBZ and CBR formats display beautifully with thumbnail views and automatic position memory.

Learn languages effectively. Read aloud using your device's text-to-speech engine, listen to embedded audio files, look up words in installed dictionaries like GoldenDict or ABBYY Lingvo, and translate passages through online services including Google Translate, Oxford, and Merriam-Webster. Musicians benefit from auto-scrolling sheet music at adjustable speeds with quick navigation between pages.

Advanced features round out the experience. Export your notes and settings, import them on another device, add a desktop widget, share pages as images, access offline Calibre libraries, stream EPUB3 multimedia content, and browse online catalogs like Project Gutenberg and ManyBooks. Open books from emails and file managers seamlessly.

With over 10 million installations and constant development, Librera: EPUB & PDF Reader is the single reader you need for every format and use case.
