eBook Reader: all in one

eBook Reader: all in one is a universal ebook reader that handles virtually every format you'll encounter—PDF, EPUB, EPUB3, MOBI, DJVU, FB2, AZW, AZW3, HTML, CBZ, CBR, XPS, ODT, and more. Built for efficiency, this reader combines all the tools you need into one lightweight app.

Reading feels natural here. Switch between traditional page-turning, smooth scrolling, text-to-speech playback through your headset, or RSVP speed reading—each mode adapts to how you prefer to consume books. The interface stays intuitive no matter which format you open. Customize everything: background colors and textures, day and night modes with separate settings, font choices and sizes, link colors, and UI themes (Light, Dark, or Ink). A Musician's mode even lets you adjust sheet-scrolling speed for music notation files.

PDF and DJVU reading goes beyond basic viewing. Reflow text for easier reading, trim unnecessary white space, split pages, zoom smoothly with two fingers, and add bookmarks, annotations, and drawings. The app intelligently handles graphics and maintains readability. An adjustable auto-scroll feature works at any speed you set, and double-tap zoom centers your view without rescaling.

Text-to-speech functionality puts audiobook-like control in your hands. Select from multiple TTS engines, adjust speed and pitch in real time, set expressive breaks at punctuation, and control playback from your Bluetooth headset. Start reading on any page with a double-tap, and let the app turn off automatically when you're done.

Manage your library with confidence. Search across books using multi-word and multi-line queries, sort by filename, title, author, size, or genre, and filter results instantly. Access online book catalogs directly in the app to search and download new titles. For power users, the app supports offline Calibre libraries with full metadata and cover display. Local and online dictionary lookups (Google Translate, Oxford, Merriam-Webster, Cambridge, and more) help you understand unfamiliar words without leaving your book.

Advanced tools round out the experience: custom CSS coding for fine-tuned page layouts, configurable tap zones, internal audiobook playback, desktop widgets, automatic session export, and the ability to share pages as image files. EPUB3 multimedia books play embedded audio and video seamlessly.
