The Premium version offers many advanced features such as voice reading aloud (Text-to-Speech), integrated Google Translate and DeepL translation, and built-in support for PDF and Comic Book formats. FBReader Premium also helps readers quickly look up words and phrases through external dictionaries, and supports full-sentence translation directly in the application – ideal for reading foreign books. The application has a highly customizable interface: change TrueType/OpenType fonts, choose your own background image, adjust brightness by swiping along the left edge of the screen, or quickly switch between day and night modes. In addition, the built-in browser and book downloader allow direct access to online ebook stores (OPDS), or users can download and save books manually in the Books folder.
