Inspired by Leonardo da Vinci’s “simplicity is the ultimate sophistication”, LibreOffice developers have focused on file simplicity as the ultimate document interoperability sophistication. This makes ODF and OOXML files written by the free office suite more robust and easier to exchange with other users than the same documents generated by other office suites.

Thanks to the efforts of developers, the XML description of a new document written by LibreOffice is 50% smaller in the case of ODF (ODT), and around 90% smaller in the case of OOXML (DOCX), in comparison with the same document generated by the leading proprietary office suite.
