I worked on improving the EPUB3 export filter in LibreOffice recently. First, thanks to Nou&Off in cooperation with a customer who made this work possible. Since the previous blog entry there have been a number of improvements around 4 topics.


The character properties of link text is now handled correctly, in the above example you can see that the text is red, and this comes from a character style.

Improved table support

Previously the support for tables was there just to not loose content, now all kinds cell, row and table properties are handled correctly. A few samples

  • custom cell width:

  • custom row height:

  • row span:


So the table support should be now decent, covering row and column spanning and various cell border properties.

Improved image support

Previously only the simplest as-character anchoring was supported. Now much more cases are handled. Two examples:

  • image borders:

  • image with a caption:


This includes various wrap types (to the extent HTML5 allows representing ODF wrap types).

Font embedding

If the user chooses to embed fonts (via File → Properties → Font → Embed), then the EPUB export now handles this. Here is a custom font that is typically not available:

All this is available in master (towards LibreOffice 6.1), or you can grab a daily build and try it out right now. :-)
