Easily create EPUBs from files supported by LibreOffice Writer via Writer2ePub

EPUB (electronic publication) is a widely used and appreciated e-book standard, file type maneuverable by numerous and numerous applications, operating systems and devices.

Via Ubuntu Software Center (and/or PPAs) users can install Calibre (a powerful e-book library management tool with in-depth file-conversion capabilities, including EPUB) and Sigil (a versatile EPUB editor with a multitude of functionalities).

Nevertheless, there are situations demanding a quick, fast yet reliable file-to-EPUB converter, in cases like reading a DOC file and saving it as EPUB and/or translating an ODT file into a mobile device's reading language (EPUB), etc.

Writer2ePub is a simplistic-yet-effective LibreOffice extension, designed with easily creating EPUBs from files opened with LibreOffice Writer in mind.

Writer2ePub comes with a wide approach, in the sense of being compatible with any format that LibreOffice Writer can open, such as ODT, DOC, DOCX, etc.

Writer2ePub has been updated to version 1.1.20, introducing numerous changes and under-the-hood improvements (across its latest releases), presenting itself as a more stable, polished and optimized extension.

After its installation, Writer2ePub pushes three icons on Writer's top-left corner, icons that are to be used for both adjusting values, as well as for generating the actual EPUB file.

In order to convert a (for instance ODT file):

  • open the ODT file via LibreOffice Writer
  • if desired, open Preferences (by hitting the red-P icon), from where various options are to be enabled/disabled
  • in order to adjust relevant values, click on the info-like middle-button, action that opens the Metadata dialog containing Title, Author, Language, Publisher, Tags, etc, essentially, a basic yet relevant set of options
  • adding a custom cover (to be displayed on the edited document's front page) is to be achieved by clicking on From file (under Cover) and selecting a preferred to-be-used-as-cover image; contrary, selecting No cover, as its name clearly says, uses no cover, selecting First image, automatically utilizes the edited document's first image as cover
  • clicking on Document Preferences, populates the dialog with a multitude of advanced features, such as Base font height, Image quality (with the on-demand option to convert images in black and white), Add index page to the ePub file, etc, basically, a panel oriented towards tweaking documents' internals

  • clicking on the first button (from left to right) and hitting the Ok button, create the EPUB file (and automatically save it in the same location as the of-origin file)

By default, creating an EPUB file, adds a W2E watermark to it, nevertheless, disabling the W2E visual mark is as simple as navigating to Preferences-->uncheck Add W2E credits at the end of the book

Due to LibreOffice's enhanced maneuverability, the user can enable the mentioned extension (when a situation requires it) and disable it (thus clearing Writer's top-left toolbar area) when there are no to-be-created documents/books.

Navigating to LibreOffice Writer-->Tools-->Extension Manager and clicking on writer2epub.oxt, highlights the extension and displays a Disable button; clicking on the Disable button, disables the extension (without uninstalling it).

Closing and reopening LibreOffice Writer, presents the Writer without Writer2ePub's toolbar icons, yet, navigating to LibreOffice Writer-->Tools-->Extension Manager and enabling the extension, displays the Writer2ePub on the toolbar.

Installing Writer2ePub is to be performed by downloading the extension, double-clicking on it and following the clickable steps.
