With Librera Reader, you can easily create self-maintained libraries of all your documents by specifying which formats to include and which folders to scan. All document collections can be viewed as a list or grid. Documents are easily identified by size- and style-adjustable thumbnail covers and detailed descriptions. Your library can be sorted by path, name, size, date, etc., and there is a filter to help locate specific documents or document groups.

While reading, documents can be locked into a vertical-scroll-only mode and their navigation set to either page- or screen-flipping. Text can be reflowed and annotated. Volume keys' functionality is configurable, and backgrounds and fonts customizable via the intuitive Settings window. Excerpts can be translated, shared, copied, and searched for on the Internet.

The best way to fully appreciate Librera Reader is to use its PRO version. You can start with Free, ad-supported one first, and decide for yourselves. We promise you won't be disappointed. Once you are convinced, please obtain a PRO license to help the app's further development.

Users feedback

Omar Alejandro Torres Garcia Is the best. Surely the most practical of all. Has read mode while the page automatically advances and that makes it special. Night mode is very comfortable not to mention automatic search books and thumbnails. The purchase and has been a good choice.

Евгений Вингловский Great reader Thank you very much for the quality of software

Алексей Титов Better can not be I take a few years. Appendix worthwhile!

Сергей Иванов One of the best programs It opens DjVu files and it is easy and without problems, do not need to wait long for each page load and then drawing the text on the other just torment (programs that can be read DjVu virtually none have several options where everything hangs and buggy and even for money) and so the files in this format is best only opened the program (tested on personal experience) so that the purchase is very happy! Thanks to those or whoever it has developed a program for good !!!

Chriss MX Okay, I never write comments on an app, but I have to this time, because PRO PDF Reader has been extremely useful for me. I tried almost all of the other PDF reader apps out there and for ease of use, stability, page rendering, and speed I could not find ANYTHING as good as the free version of this app (PDF Reader). I bought the Pro version not because I found the ads annoying (they really weren't - and I HATE ads) but because I wanted to support Mr. Ivanenko's future efforts. Great job on the app and I look forward to your next project!
