Librera
An app that opens PDFs, EPUBs and comic files on Android for free.
What Librera does
Librera is a free ebook and document reader for Android. It opens PDF, EPUB, MOBI, FB2, DjVu and comic archive files, reads books aloud with your phone's voice, and connects to online OPDS catalogs. It's free with ads.
Librera is a solid free pick when your books come in lots of formats. PDFs, EPUBs, MOBI, FB2, DjVu and CBZ or CBR comics all open in the same app.
It reads text aloud using your phone's built-in text to speech, which is handy for long PDFs. There are plenty of display, bookmark and note options, and you can export and import your settings. OPDS support lets you browse online libraries of ebooks from inside the app.
The free version shows ads, and it's Android only. Compared with ReadEra, it's less polished but very flexible. It also makes a good backup reader to keep around for the odd file another app refuses to open.
