Librera Reader is exceptionally versatile; it can read professional file formats such as EPUB, EPUB3, PDF and MOBI. Additionally, the application can read IBA files, which are a popular format that only Amazon can produce. Both EPUB and AZW3 are well-known professional ebook formats that are exclusively owned by them. The reason why these two formats are similar to MOBI is because they both support video-enabled and audio-enabled ebooks. Additionally, Librera Reader can read files in the IBA format, which make it one of the most versatile applications currently available. Apple’s iBooks Author program created the IBA book format. However, this popular book format is not widely used due to its limitations with programming code. IBA is a popular ebook format that Apple’s iBooks Author program can create books in. There are other very rare ebook formats supported in this program such as CBZ, XPS, TXT and FB2. Other popular formats supported by this application are CBR, FB2, HTML and MHT. It can be said that Librera Reader is one of the few mobile applications that support one of the most available ebook file formats. This app features a plethora of features that make it highly versatile. From downloading new files to interfering with the file's content, this app can help users with translating documents written in foreign languages, even when they're not connected to the internet. Additionally, users can bookmark pages and change text files— no matter where they are or what file type they are. When working hands-free with the TTS Engine system, this software reads the data file to you. It also remembers where you left off when your hands are occupied. This is one of the many convenient features of the program that makes it popular with its users. Confusingly designed programs and websites frustrate their users and force them to continue looking for where they left off. By using this software, users no longer have to deal with this problem. The document search function built into this application works very well. When someone has a large amount of ebook files to locate, the search function makes finding information easier. All they need to do is enter the name of their ebook file format into the taskbar. The search engine quickly finds results and returns them almost immediately. Keys can be used to access keyword searches, which quickly reveal specific pieces of information within a file. This functionality is accessible through the data files function. When performing a keyword search, information related to the search term immediately appears on the phone's display. Librera includes the ability to read and visually interpret music files with lyrics and tabulature. With Librera's custom scrolling speed options, you can easily read music with lyrics that might be hard to understand.

Librera Reader's grid-like interface makes finding specific ebooks very easy. You can customize the program's folders to arrange them how you prefer; alternatively, the program sorts your ebooks for you. Additionally, you can place your most used folders at the top of the list. This is an ease-of-use program with customizable settings. It also comes in two versions: Day Mode and Night Mode. In Day Mode, the document's background is light; its text is set against a white background. The colors appear vivid and full. In Night Mode, everything is darkened or the blue filter is in place to reduce exposure to light. This provides comfort during application by decreasing sensitivity to light. Additionally, users can choose between two interface styles— one with a blue filter and one without. As a multifaceted reader, Librera Reader has high customizability. You can use it for any task that requires multiple documents— from school to work. It also has strong usability due to its mobile app.
