Exclusive Librera PRO Capabilities

Try it yourself to fully appreciate what it can do.

These two formats, similar to MOBI, allow ebooks to include video and audio. Librera Reader’s support for the IBA file format helps it stand out as one of the more complete reading solutions available.

The IBA ebook format was created with Apple’s iBooks Author tool. Even though it’s used for ebook creation, it hasn’t been widely adopted—partly because of limitations related to code handling.

Still, iBooks Author can produce books in iBooks Author (IBA) format, which has a strong presence in the ebook publishing workflow.

Read Many Different Formats

Librera PRO can open a wide range of ebook types. Beyond the most common formats, it also supports less typical ones such as CBZ, XPS, TXT, and FB2.

It can also handle several widely used formats, including CBR, FB2, HTML, and MHT. As a mobile app, Librera Reader is among the few options that can read the most popular ebook file types while offering a flexible, feature-rich experience.

You can translate foreign-language documents, download new files, and edit existing content—without needing an internet connection.

User Feedback on Librera

• “It used to show a notification option that let me move forward a page while listening, but that prompt doesn’t appear anymore. Overall, it would be great to have a ‘skip half a page’ option instead of needing to enlarge the words. It sometimes fails to move forward when reading documents/epubs, and the ‘replacements’ in read-aloud can act strangely. Still, it’s my absolute favorite app.”

• “A fantastic and versatile reading program with lots of features and many file formats. It has been especially helpful for my dyslexia and low vision. Definitely worth trying—you’ll love it. It preserves sketches, diagrams, and photos, and it’s great for reading PDFs, ebooks, and even comic books. The text formatting options are excellent.”

• “This app is awesome and reads all the most used ebook formats and more. The main issues I’ve noticed are that I can’t add one of my folders. It reads the books in the folder, but doesn’t add them into the library. Also, it doesn’t seem to fit properly to width. That said, I really like the scrolling and the traditional book-reading options.”

Wonderful Highlights

• Custom colors for foreground/background (solid or textured)
• Zoom behavior, including automatic and manual centering when zooming in
• Vertical scroll lock for a steadier reading experience
• Single-page view for documents that normally show two pages/spreads



• Page turning that can be based on pages or screens
• Configurable volume controls for the reading voice

Conclusion

Librera PRO supports custom CSS, giving you more control over typography and layout—especially helpful for EPUB/HTML content. You can also create your own tags, organize books by tag, and filter or sort your library by things like path, name, size, date, and other criteria.

Thumbnails with cover previews and detailed descriptions make it easier to locate the documents you want quickly.
