ReadEra – book reader pdf epub is an e-book reader application by READERA LLC that lets users open and read books and documents in a wide range of formats on Android devices. It handles PDF, EPUB, Microsoft Word (DOC, DOCX, RTF), Kindle (MOBI, AZW3), DJVU, FB2, TXT, ODT and CHM files, and it also works with books and documents stored inside zip archives without requiring users to unpack them first. The app is designed for offline reading and does not require an account or registration.
The reader includes a built-in library manager that automatically detects books and documents on the device, groups them by author and series, and organizes them into reading lists such as To Read, Have Read, and Favorites. Users can also create personal collections, add the same title to several collections, and browse files through folders and downloads. Navigation tools include a table of contents, bookmarks, text highlights, quotes, notes, and a reading history, with a progress line and page pointer for moving through a book.
Reading settings cover day, night, sepia, and console color modes, horizontal or vertical page turning, and adjustments for orientation, brightness, and margins. Font type, size, weight, line spacing, and hyphenation can be changed for several formats, while PDF and DjVu files support zoom and margin cropping. The app saves the current reading position even if files are moved or deleted, avoids duplicating books in its own storage, and supports storing data on an SD card. A multi-document mode allows reading more than one book or document at a time, such as in split-screen view.

ReadEra is aimed at Android users who want a single offline reader for e-books and documents across many formats, including people who keep a personal library of EPUB or Kindle books, students and professionals who open PDF or Word files, and readers who prefer no ads, no in-app purchases, and no account registration. It is also suitable for users who read several titles at once or want their reading position preserved when files are moved or deleted.
Use the library manager to let the app detect books and documents automatically, then sort them into reading lists or collections. Adjust color mode, brightness, margins, and font settings for each format to make long reading sessions more comfortable. If you read scanned PDFs, try the single-column mode and margin cropping. Keep in mind that moving or deleting files will not erase your bookmarks or last-read page, so you can continue where you left off after re-downloading a book.
