Book Reader: viewing EPUB and FB2 files in a dedicated reader

ONLYOFFICE Apps provides you with a Book Reader plugin that can open EPUB and FB2 files in a dedicated reader, including compressed formats (.fb2.zip files and ZIP archives containing EPUB or FB2 books).

Configuring Book Reader​

System plugins are enabled in the workspace settings by the owner and administrators. Once enabled, they are available to all users across the apps that support them.

  1. Go to Settings -> Integration -> Plugins.
  2. Click the toggle next to the book-reader plugin to activate it.

To start working with the plugin, you do not need to change the default settings. To view the plugin metadata, click the gear icon next to the book-reader plugin.

  • .epub - Electronic Publication (EPUB 2.0/3.0)
